Susuwataries with magnets (10*2,5mm). One version with magnet in the back (fridge magnet) and one version with magnet in the bottom.

Arms are black 1.75mm filament

Cavitys for magnets are added in BambuStudio, so its easy to change to fit your own size of magnets.

Included Blend file for those who wants it :) also includes a third bigger version with printable arms

File is not cleaned, so… yeah…

STL added upon request. Stls DO NOT have holes for arms nor magnets. those cavitys are made with “negative part” in your slicer.
