Back brace Reinforcement for Taz 1-6 Printers and other 20mm extrusion frames

thingiverse

This project offers a budget-friendly solution for significantly enhancing the upper gantry and Z-axis stiffness of the Taz frame in all model Taz printers. It utilizes three 20mm surplus Taz extrusions (three 500mm or one 510mm, along with two 500mm for a Taz 6 specifically), fifty-five millimeter long M5 cap head bolts, M5 flange nuts, ten millimeter long M5 cap head bolts, M5 t-nuts, and M5 washers. Additionally, it requires two stick-on furniture feet (the Taz 6 flexifeet edition will be available soon) and approximately one pound of plastic material. Any type of plastic can be used for this project, including PLA; I employed Push Plastics Black ABS. Prior to printing the backbrace project, I would have stated that it was unnecessary. I print at very high speeds generally (averaging 120mm per second with higher moves and slower first layers being my standard "medium" speed). Consequently, I sought a means to reinforce the frame against even greater forces. Following the installation of this reinforcement, my prints exhibit no layer offset whatsoever. I had already achieved a good level of calibration using the openbuilds mods, but this addition has taken it to the next level.
