Reinforced fold out spool Arm with Teflon Liner

thingiverse

I damaged my spool holder for my Taz and had to fabricate another one. This one is heavily fortified to handle full 5lb rolls at high machine speeds. It employs a half-round piece of Teflon and a press-fit bushing that was taken from the stock Taz arm, but you can probably find similar ones at McMaster Carr, which also sells suitable Teflon. The Teflon half-round is approximately 1/4 inch in diameter. Mine simply slides into place, held down by gravity and a side slot chamfer. You could glue it if you prefer, but it's Teflon. I strongly suggest printing this with the strongest material available. PLA may not be suitable for long-term use. It uses an M5 bolt to mount to any suitable 20mm frame and can also work well on flat surfaces with a washer.
