Taz 5 Repair Parts
There are a significant amount of issues wrong with the Taz - all bushings are significantly worn, all the belts are cracked, all extruder parts are broken, etc. This is a seriously great printer let down by next to maintenance for a very long time.
I propose a budget of $266.04 + a roll of PETG for spare parts, which also allows us to upgrade the Taz 5 to a 5.5 - there are a few issues with the Taz which were upgraded between revisions. The biggest change is upgrading the X/Y smooth rods to 12mm instead of 10mm (taking the X sag from around 0.1mm to almost nothing). At the same time, we can increase the belt width from 6>9mm for a tiny bit extra than just replacing the belts with 6mm, which will allow us to drive the printer a little bit faster and reduce ringing.

For the filament, I am happy to do all the printing at home in PETG as my printer is set up for it, and I am happy to leave prints running overnight. I am about to order some filament, so I am happy to cover postage costs if I’m reimbursed for the filament (1kg of PETG is about $34 from Cubic Technologies). I think total weight of required filament is about 400g for all the parts, so once they’re done I will bring the rest of the roll in.
There are a few bolts/etc which probably need to be replaced, but I am sure I’ve got most of them at home I can just donate to the Space.
