Sewing Machine Motor Brush Pilot and Motor Stand
By Dennis P
at 2024-05-06
Motor stand for working on the typical 1/4" shaft, universal sewing machine motor.
Pilot bushing for removing and holding the carbon motor brushes. The bushing allows the spring loaded brushes to remain in the proper place and allow for worry free removal and installation of the carrier plate.
The pictures will explain it better than I could write it. 2-4 Photo sequence is the removal of the carrier plate. Installation is reverse of this operation.
Technical
Print inverted so that the solid surfaces are on the build platform.
Print in your favorite material using 0.4mm extrusion width, 3 shells.
Break away support plug is modeled on the motor stand, 0.2mm gap.
Use 12-15% infill. It does not do much other than hold up the top faces when printing.
