Bearing (608) with Beads (Ikea Pyssla or Hama Ironing Beads)

thingiverse

A bearing with the same dimensions as the widely used 608 (OD: 22 mm, ID: 8 mm, height: 7 mm). I am using ironing beads (i.e. Hama or Ikea Pyssla) as rolling aids. The elastic ones don't work very well, better use hard ones. Inspired by the often found BB-ball bearings, but I only had the beads at hand and had rolly needs... Obviously only for light duty applications, like helping a spool holder, etc. This can be challenging to print, because of the overhangs. I went through a few iterations and found that supports from the slicer don't help at all. I have added little tabs to cut away - they function as bridges. Also set to print with 3 perimeter layers, this worked for me (basically 100% infill, but no structure). To fill in the beads a wooden skewer or tweezers are very helpful. Fill in a few beads, then hold tightly and add the rest through the opening. Tolerances are quite high to account for the not completely even beads. You can cut the supports before or after adding the beads. Please excuse the overlapping surfaces etc. of the model. Still very new to blender and 3d modeling.
