Stepperonline NEMA23 Strain Relief

I recently bought a NEMA23 motor from Stepperonline. I like the motor just fine but the stock "strain relief" was appallingly bad to possibly even making it worse. So I decided to draw & print my own version. This design allows the cord to go toward or away from the main motor face, your choice.

These motor part numbers appear to be compatible:
23HM20-0384D
23HS22-2804D
23HS22-2804D-B200
23HS22-2804S
23HS30-2804D
23HS30-2804D-B200
23HS45-4204D
