The stock hand crank (for dust filter cleaning) is too long and hits the wall (with the angle I installed it at). I designed a shorter one.

Features:

• Smooth turning with a 608 bearing in the handle
• ~ 12 cm handle length (half that of the OEM one)
• fits 12mm diameter shaft with ~1mm notch

Hardware Required:

• a 608 bearing
• M8 x 30mm bolt

Print Setting:

• PETG preferred
• 0.4mm nozzle
• 4 perimeter, 25% infill
• Print at 101% or 102% if the fit is too tight with PETG (especially the handle, long bolt might be tight fit)

Note:

• the print file contains 3 individual objects.
• 3D preview shows the assembled view.
