A replacement spoolholder for the UM2 which offers very little resistance when unspooling.
Update: Added parts for 608 bearings and associated hardwa...re.
Update2: hreedjik has created a mount for the UM1: http://www.thingiverse.com/thing:251409
Print, screw together, mount and keep printing. Not much to it really..
3d model print parameters
In addition to the printed parts you will need:
- 2x 626 bearings (cheap on Ebay)
- 1x 6mm threaded rod, 95+mm long
- 3x M6 nuts
OR for th...e "608" parts:
- 2x 608 bearings
- 1x 8mm threaded rod, 95+mm long (better to cut after assembling to make sure)
- 3x M8 nuts
Please note that I haven't printed and tested the 608 parts as I don't have the hardware for those at the moment.
