A simple spool holder for the Mendel90 Lasercut

I have done a detailed blog post as an introduction to OpenSCAD, using this design as a worked example. Check it out, any feedback is appreciated:

By changing variables in the the OpenSCAD script or using the customiser you can use different spool sizes and either 624 or 608 bearings.

I have been using this for 2.3kg filament spools and multiple small spools quire sucessfully, for the small spools the bearings are not actually required - use it as an over engineered peg.


The included stls are ready to go for 624ZZ bearings for a large (120mm dia) or smaller (50mm dia) spool. or use customiser or edit the SCAD to produce one for 608 bearings or a different spool size.

For the bearings:
4 624ZZ bearings, 4 M4 washers, 2 M4x30mm bolts and 2 M4 nyloc nuts

To mount:
4 M3x20mm bolts, 4 M3 washers, 4 M3 nyloc nuts.

Once printed use the mounting plate end as a template to make holes to drill in the printer frame

Thank you for sharing nice design! I printed 608zz version and found that outer diameter in scad file is wrong. OD of 608zz is 22mm.

Hey Thanks for pointing that out, i have updated the scad file so customiser should work properly.
