PrintShift 3.0 Build Series: Step 1

This page details how to print the PrintShift parts. I like to print the parts on the Prusa Mini that’s destined to be PrintShift-ed - that way you know the machine is up and running and ready to go. If your mini’s acting up or failing in any way… repair it before you upgrade it!

Materials Needed

  1. Prusa Mini. Yeah. The whole thing.
    • Prusa sells ‘em mostly built: Prusa Mini+
    • Or barely assembled: Prusa Mini+ Kit
    • The mostly built goes together in under an hour; kit is maybe ten hours of building.
  2. Filament!
    • You need some high-temperature filament like ABS, PETG, ASA or better for the bed-touching components.
    • You need some stiff filament for the Motor Mount and Standoff - PLA is fine, pretty much anything except TPU.

Tools Needed

  1. The Prusa Mini includes all the tools that you’ll need for this portion of the build :-)
    • I do generally use my own 2.5mm allen wrench
    • And some side cutters to trim the zip tie


  1. Build your Prusa Mini! Just follow Prusa’s instructions
  2. Test Print! Prusa includes a few on the USB stick that comes with the printer.
  3. Print Large PrintShift Parts
  4. Print PrintShift - all small parts
    • This is all of the other parts; they need to handle the higher temperatures of the bed, so must be ABS, ASA, PETG or similar.
    • Mine are printed in blue ABS, .25mm layers, 3 perimeters, 50% cubic infill. They need to be strong, rigid, and stable up to 100C.
    • Small Parts
  5. Print (optional) Raspberry Pi components
  6. Gather the rest of the parts from the Bill of Materials and start Building the Belt!
