What are you printing this week?

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.

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)

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.
