Finer the layers the higher the pitch of the wizzzzzz. .16mm with a .4mm nozzles sounds great to me. Bearings will spin faster if you remove some of the grease. A little bit of WD-40 and some heat will cook off most of the grease.

Required parts: 

  • 8x 688-2RS 8x16x5 bearings

  • 2x M3x20mm button head screws (shorter works but longer provides more support)

  • 6x M3x10mm button head screws

Optional parts

  • 2x 7x17x6mm thrust bearings

for commercial use, contact me
