T-Slot Filament Spool holder M8 and American Standard Size

This spool holder will let you use larger spools in addition to smaller spools.

Our local stores don't stock M8 threaded rods, so I decided to support common American-size threaded rods and nuts in addition to Metric.

Required hardware:

Dual Setup: (see picture)
1x 3/8 threaded rod, 10 inch
8x 9/16 nuts
6x 3/8 washers

4x Spool_caps
1x Spool_holder_body
1x feed_tube_spinner
1x feeder

*for M8 setup, replace all hardware with M8 nuts, washers, and rods!
