Description

This project is a low cost option for adding significant upper gantry and Z axis stiffness to the Taz frame for all model Taz printers. it uses 3 20mm surplus Taz extrusion (3x 500mm or 1x 510mm and 2x500mm for a Taz 6 specifically) some 55mm long M5 cap head bolts and m5 flange nuts, some 10mm long M5 Cap head bolts and M5 t-nuts and M5 washers (possibly shorter than 10mm i was just grabbing them from the container, will measure when i get a chance), 2 stick on furniture feet (taz 6 flexifeet edition coming soon) and about 1lb of plastic. Any type of plastic should be fine for this application, including PLA. I used Push plastics Black ABS.

Do you need this backbrace project? Prior to printing it, I would have said no. I print at very high speeds generally (120mm/sec on average with higher moves, slower first layer is my general "medium" speed) , so I was looking for a way to reinforce the frame against even higher forces. After bolting this on though, my prints have absolutely no layer offset at all. I was already pretty well dialed in with the openbulilds mods, but this pushes it to the next level.
