Spool hub and holder. 52.5, 56.5 mm by galaxius

Last crawled date: 3 years ago

This has been superseded by my much easier to use new design http://www.thingiverse.com/thing:550851
(UPDATED: Less filament use and additional hub size)
This hub allows you to change your spool without having to take all the nuts and bearings off. The slot allows it to be inserted into position on the rod and then insert the bearing to the hub and the hub to the spool, the nut is used to keep the hub in place. The bearing housing is 22.4mm to allow the bearing to be inserted/removed by hand.
The hubs fit a spool with a 52.5mm or 56.5mm hole, my filament is from www.3DPrinterGear.com.au
Printed in PLA with 2 perimeters/top/bottom and 25% infill, no support required.
Parts:
1 x 5/16 or 8mm threaded rod.
4 x lock nuts for locating on the uprights (this will depend on how you design/build your spool holder, the base bracket I used is the Robo3D base bracket I designed.
2 x nuts per spool.
2 x 608 bearings per spool.
2 x hub per spool.
