Well, now you can use them on your spool holder!Requires: 2 608 bearings 6 m3x15mm+ screws 3 m3 nuts, washersDirections:Notes: If anyone wants a step file of the spacer, I can, or different dimensions, there are many openscad ones, this was done in inventor. I have a few ideas for improvements to try soon..Uploaded new version (stl and ipt, so the download counter reset), fits all the variances in spool sizes (instead of only the largest ones - Glow), and has all holes chamfered for better printing.
