For Christmas, my Mom & Dad gifted me a 3D printer. On Black Friday, mid Californian-roadtrip, I put in the order for an Ender 5 Pro with spools of black and white PLA filament. Sorry, but I was unable to contain my excitement and wait until Jesus’ supposed Birthday before using it
Feb 4, 2023
I saw a YouTube short showing these off and they looked handy. The design calls for some nuts and bolts which I don’t have any kits, so purchased this one which should come in handy for future projects too. Creating two better knobs, two caps, a body, and a holder will require
20g PLA filament, a
1" thick sandpaper strip, two
M4x20 bolts, and four
M4 nuts. I ended up Gorilla gluing the bottom nut. I used so much that it impacted the fit of the caps and had to cut away at the solidified glue with a knife and sand the base flat. I also labelled them with their grit using my Dymo I’ve been obsessed with.
Nut + Bolt Measuring Tool
Feb 2, 2023
The kit of nuts and bolts I bought arrived in a completely entropic state despite the organiser box it came in’s best efforts. To fight entropy I printed this metric nut and bolt measuring tool that will be stress tested on 480 pieces! Unfortunately I didn’t switch to black filament when it started oozing on the glyphs, so I precisely used a black pen.
Camera Hot Shoe Cover
Jan 20, 2023
I lost it! I’ve been using a little battery powered LED light that I got from work and use mainly for the odd work video call I make. I thought I stored it with my other camera stuff but it’s not there. Luckily, printing another should be piece of cake. I am now also noticing the LED light has 3 additional hot shoe mounts on it which I could have used to store the cover… Oh well, c’est la vie!
Now Spinning Shelf
Oct 26, 2022
I added a bunch of hexagon holes to the piece so it would print faster… That’s apparently a myth. They only save on material. That blog post says a good rule of thumb is adding surface area, which the “speed holes” do, increases print time.
Do the speed holes add surface area?
Shower Knob V2
Oct 23, 2022
After about 4 months it started getting loose and then one of the arms snapped, leading to its death on
Oct 1, 2022.
“It wasn’t Heather-proof” - @BarrSouth
I will attempt to ameliorate the loosening by making sure I use a high infill percentage. To strengthen the knob I will be making it more of a disk shape so the force hopefully distributes more evenly than before. I will also add vertical supports to each “prong” since to open and close the water you move the knob up and down respectively.
The original shower knob was one of the first things I designed myself, and so in my beginner shortsighted mind I apparently did not save it anywhere… I might have the design I made on paper with measurements somewhere, but that’s like finding a needle in a haystack Luckily, after some rummaging I was able to find my first prototype replica of the actual main connection to the metal level of the shower apparatus, which I can take measurements from and import a photograph to get back to what I love most, showering
Not completely happy with how the front looks, maybe I should have printed it flipped. Or I could add faces to it kinda like a Beyblade
How can I try to avoid losing as much data as possible? Document measurements I take? I really should probably switch from Shapr 3D to Fusion 360 so I can make parametric models, making design tweaking vastly easier, working with Play-Doh vs. Marble.
Toilet Bolt Covers
Jun 7, 2022
The existing covers were pretty nasty so I threw them out several months ago and have been rocking the bare metal setup - just another step to boujee up my place! I took some inspiration from these two I found on Thingiverse.
Just went with a random shape, that was able to conceal the bolt, nut and washer. I could sand and polish it to get it to look closer to the porcelain bowl once I acquire polish and the varying degrees of grit sandpaper (200-3000). Spent about 5 minutes getting the measurements and designing it and kicking off the print. I was tempted to duplicate the model in my slicing software (since I need two of these) and run both at once but it’s good practice to ensure the design works first before wasting material on a part that potentially doesn’t get the job done.
In fact, the resulting print did not fit. The measurements were right though for some reason the printed piece had an inner diameter of
9.74mm when I modeled it to be
11.2mm. My quick and lazy fix was to increase both the X and Y scale by
1.15x in my slicing software, which hopefully gets the right size…
I also have a regret on my model design since it has a crevice that will make it a little harder to clean - a design principal that I think about an unhealthy amount. If it wasn’t already the next day (12:02 AM) then I might redesign it but I already have to stay up until this print finishes to test the fit, then hopefully just kick off another of the same print right after so I can make it to bed before the boogeyman gets me
Bear Spray Safety Clip
May 26, 2022
For @katiekatie12341. She asked if I could print and mail her a safety clip for her bear spray since they don’t ship to Canada. C’mon UDAP, figure it out! Anyways, the model was already available on Thingiverse so printed this at 15% infill and with four shells as the creator recommended. Mailed to her friend in North Vancouver and hopefully know her bear spray never goes off unintentionally
PS: I was happy to help and more just happy to be thought of as someone people are comfortable reaching out to and asking for my help
May 24, 2022
I broke my shower tap. Now it’s just this metal thing. Luckily I had a spare wrench and have been using that, just as my landlord ended up suggesting!
It’s not very classy or as convenient though. Time to print something up! First I replicated the part that went over the metal arm to make the prototyping phase faster. Once that piece was worked out I extended some knobs off it for the final product.
Maze First Print
Dec 5, 2021
Now that the construction part is complete, I’ll run a test print! Since this is the first print, I must calibrate the print head to be only slightly above the print bed in its home position. Once that’s done, I set the extruder temperature to 205° C and guide the filament through the tube to the print head until some begins to extrude. The printer came with a micro SD card and a USB adapter for it. The files included on it were the Creality Slicer application, several STL files and some already pre-sliced files. I decided to go with the 10x10 maze since it only takes an hour to complete and uses minimal filament, since my goal was just to see if the thing worked. After slicing and exporting the file to the micro SD card, I plugged it into the Ender 5 Pro and selected it from the menu and waited the hour. Great success
Here are all the things I have printed so far in chronological order and the
.stl files of my designs.
So far I’ve been designing in Shapr 3D on iPad, which has been pretty good and beginner friendly. However, now I’m seeing the great benefits of making parametric designs so will probably switch to Fusion360 when the model calls for it and I’m on a computer.
Why 3D Print Stuff
It’s a great and simple enough way to make things. The things you can make are only limited to the size of the printing area, the filament materials, physics, your imagination, and your CAD skills, in the unlikely scenario where someone hasn’t already designed what you want and graciously uploaded to the Internet for free.
I can definitely see more households getting 3D printers in the future. I’m sure it has gotten loads easier in the past several years, but an easy mode and directory/catalog of parts to print or scanning something to duplicate with your phone would really elevate the accessibility. You can create so many things out of a common resource, being the plastic filament. It would also reduce the amount of shipping that occurs. Say you needed to buy a soap dish, a hair clip, and a tiny thingamajigger for your dishwasher that you can only get from this one store 40 minutes away and they are out of stock and it costs like $50. That sounds kinda lame. You would have to drive to 3 different stores or have them all delivered. I imagine that carbon footprint is pretty large for the comparatively small items you need. A more efficient way to get these items if you already had a 3D printer would be to download some 3D models, that hopefully already exist, and buy a multipurpose spool of plastic and run the printer overnight. The shipping cost then becomes more like a one-time fee for the spool and the prints are probably faster than someone driving it to your doorstep anyway.
This is likely an oversimplification, not including how plastic is made. I haven’t seen that episode yet.
- Smaller environmental impact due to less shipping (electricity costs?)
- Potentially faster than buying from a store or online
- More convenient
- Ease of use (calibrating perfect settings, needing a computer with specific software and an SD card to transfer the files)
- Small size items only
- Smaller volume of operations, injection moulding plastic is much more efficient at high scale
Unboxing + Building + Setup
First of all I need to unbox and build the printer. This ended up being much easier than I anticipated. As much of the printer was already pre-assembled as possible and only required me to screw in the base to the top, add the print bed, control unit with screen, and connect all the cables. The cables were pretty well labelled, but I still managed to mix up the print head thermistor with the print bed thermistor The packaging was also superb and included a 200 g spool of PLA to get started.
Not including the dumbbells!
I’ve never used one before and the only experience I have 3D modelling was a couple days in Grade 9 tech class using
AutoCAD to design a rudimentary airplane that I would later realise in wood. I’m excited for all the possibilities having a 3D printer will unlock. There are several 3D printers at the Microsoft Garage in Redmond that I could also be making use of… then again, most of my inspiration comes at inopportune times.
- Copy all the configuration files to
/Marlin/and overwrite existing files
- Install the
PlatformIO IDEextension to VS Code
Build(opening the tasks took a long time - just says
- Copy the latest file named
/.pio/STM32F103RC_creality/firmware-YYYYMMDD-HHmmss.binto the SD card’s root directory with the name
- To begin the update, insert the SD card and turn on the printer
I’m running OctoPrint on my computer with a
10ft Micro-USB cable connecting it to my printer. I throw the printer in my closet whenever I’m not using it to save space.
I also have the printer plugged into a smart outlet, this can allow me to turn off my printer once a print is done. Otherwise, the fans will continue to run - the firmware doesn’t have an option to do this natively :sad:
I will definitely have a mindset of can I build this myself now whenever I have the desire to buy something. Not only would it be more fun to do, it could also be more convenient depending on the circumstances and also self-sufficient. If you want something done right, do it yourself
