Replacing threaded rods on Lulzbot Taz 4

I got a used Lulzbot Taz 4 from Noe and Pedro Ruiz(https://www.youtube.com/playlist?list=PLjF7R1fz_OOVgpmWevin2slopw_A3-A8Y) that needed some repairs. In this video I am replacing the threaded rods.

3D Printed Raspberry Pi Zero Face Case

I designed the case for a Raspberry Pi Zero in Fusion 360. Design inspiration was from a previous Adafruit designed Raspberry Pi Face case for the B+ model. Noe Ruiz helped with showing me some design changes that could be made to improve on my original sketch. I also used the snap fit design shown on a Layer by Layer video to make the case so it requires no hardware to assemble.
