OnStep Smart Hand Controller Case

I have finalized my Smart Hand Controller case! This is a design that is made for 3D printing. I highly recommend using PETG filament since PLA does not do well in extreme temperatures and UV exposure.

Additional Parts i used:

RJ11 Connector
USB Board

M3 25mm and 18mm self tapping screws for plastic.

I have the 3D files hosted on Prusaprinters so you can print this case.


If you don’t have a 3D printer or want to use a 3rd party service I can print you the parts plus the RJ11 and USB connector.


  • PETG printed parts. Available colors are Orange and Black. You can specify in your order what colors you want.
  • Stainless Steel Screws
  • RJ11 Connector
  • USB Connector
  • (SHC board and screen is not included. You can find out how to build one at this address: https://onstep.groups.io/g/main/wiki)

Cost is $40. Please allow 48 hours for order shipping information. For international orders outside of the USA please contact me first for shipping estimates.
