When disassembling the MK4s to convert to the CoreOne one of the pulleys was stuck on the motor shaft. Instead of yanking on the shaft I designed and printed this simple puller to print on the Mini+. Printed in PETG with 40% fill, flat side down no supports.
Requires a M4 x 20mm screw and M4 nut to complete..
CAUTION: When using the puller make sure the M4 screw is centered on the shaft to prevent damage to the soft aluminum pulley.
