A simple spool holder using a tried and tested design, using 8mm rod and 608 roller bearings (the kind you find in skateboards, rollerskates, etc.)
The SCAD file for making a spool clamp to your exact specifications is in the remix source. I have created two spool clamps that fit most filament spools such as eSun and Aurarum (the filament brands I use).
Bill of Materials
1 x Rod Holder
2 x Spool Clamps
Hardware / Not Printed
1 x 8mm threaded rod - approx 140mm (slimline clamp) or 160mm (standard clamp)
2 x 608 bearings (I got mine from an old skateboard in a thrift shop for $1)
4 x 8mm washers
2 x 8mm nuts
1 x 8mm wing nut
- Thread a nut and a washer onto the rod, slide it into the printed mount (flush side) so that almost all the thread sticks out from the side with the recess
- Thread a washer and a nut onto the rod, from the recessed side. Do it up hand tight, then use two spanners to tighten the two nuts solidly together.
- Press fit the 608 bearings into the two spool clamps.
- Thread a washer onto the rod, then a spool clamp.
- This is where you would put your filament spool
- Thread a spool clamp onto the rod, then a washer, then the wing nut. Do up the wing nut.
Your filament is now secure. To remove the filament, do steps 4-6 backwards.
