Spool holder and line guide for prinrbot plus

thingiverse

This is a fantastic little spool holder and line guide that I've developed after experimenting with other designs that didn't quite work out for me. The tolerances of the threaded rod are adjusted by .2mm to compensate for shrinkage factors. The threaded rod itself is 6.1 mm in diameter, available at your local hardware store, where I found mine; you'll need four of them, each about 80mm long, and 16 nuts - longer if using a wider spool, like my 54.5mm wide one. It took some time to find the right bearings; I ended up getting all four from Fastenal product ID "608 ZZ" and they have impressive characteristics: 8mm ID x 22mm. However, I encountered an issue with the line guide hole not popping out easily but an exacto knife fixed that for me.
