Cat Deterrent model I designed since one cat dive bombs from door edge semi frequently. At some point will probably release the 3d models for it. Designed it in Alibre Design Pro.

Designed a model railroad car that holds a Raspberry Pi Zero and camera module for first person view in real time from a model train. My dad and I have been working on this concept for a while and my latest idea was to put a micro servo on it to steer the camera. We 3D printed a mount with swivel for the camera that holds a servo and bent some stiff wire to make linkages.
My most recent improvement to the design was learning how to use Blender enough to model a 3-part power supply box to house a series of electrical modules to convert the track power into a stable 5V for the Pi and condensed it into a small box that fits on the car alongside the Pi and camera system. The box contains a rectifier, switching regulator module, lithium battery charger module, and battery.
I also modified a model railroad truck (wheel assembly) model I found on Thingiverse to add DIY power pickups, bent a bare copper wire into a makeshift spring that contacts the wheels and a place for the wires to attach that feed the power box.
Wow, that's really cool! You should totally post pictures or a video.
I made a post a few weeks back for our original design:

I haven't posted anything about my new design though, as I made my own flatbed car model while that one was a model I found on Thingiverse. The power circuitry was also on a separate car in that test which is why I made my power box design. The model railroad layout is at my parents' house so I have a short loop of test track I've been using to test my new design at my house which is absolutely not as interesting.
@mibzman Mostly temperature towers, honestly. I've been playing with PHA, so I printed temperature towers for two new colours of that, and also I subscribe to the protopasta "endless filament" programme (at 150g/month, supersized samples really but I like it) and those showed up so needed one for each of them.
I _really_ like the bottle colours they sent out this month, particularly the blue. Just gorgeous.
@fedops @mibzman PHA is _pretty interesting_. More heat tolerance even than HTPLAs, but definitely also more flexible at all temperatures, which can be a plus or a minus - it's kind of like a less-flexible but more-durable nylon, I think? I haven't worked with nylon but from descriptions.
It also really wants a 0.6mm nozzle, though I have found - and this is what I did for these temperature towers - that the non-wood-infill PHAs can be consistently successfully printed with a 0.5mm nozzle, if the model is sliced for 0.4mm.
Also: Sure! I'd expect the pictures to work on actual Mastodon. But they didn't make it to Lemmy replies. Don't know if Lemmy even supports pictures in replies locally tho xD
@fedops @mibzman If you want to grab this purchase-advice reddit post before the walkout for later reading (or come back to it on Thursday), it isn't bad at all, even if OP's hate-on for Creality is overwrought. (It's also not completely insane, but.)

@moira thanks, yeah! My preferences align quite well with that, interesting. 😄
The Neptune and Sovol are high on the list, though I am strangely fascinated by Deltas (I partly blame @Tay0 for that) and Klipper so the V400 is at the top right now. Prusa would be a good choice also I'm sure, I know a couple ppl who have them and like them a lot.

Its been a busy week! Prior to finishing this Super Mario Bros light, I had to print and modify a BLTouch mount to replace my Artillery Sidewinder probe that went bad for the second time. Then I swapped out the warped glass bed for an aluminum bed with a PEI magnet sheet. Finally, I printed a mount for my Pi Cam after having it Scotch taped to my desk next to the printer for the last year or so.
Just have to finish up the power wiring on the light:
I am trying to improve my lithophane business card. Only one Crash so far...
Also planning on printing a TPU version of a keychain I designed that is an Atari Controller. It’s too fragile for a pocket in normal filament. Wish I had a tool changer, so it’s going to just be all black I think. [https://www.printables.com/model/491788-atari-joystick-key-chain-with-no-key-chain-option](Atari Keychain)
