Design preview. Rendered from the file, not a photo.
The maker says it fits: RepRap Prusa Mendel. See the proof
This model is not currently offered as a verified ready to buy print.
What it does
- Holds hex bits and M8 nut wrench in one tool, so you keep both hands free to work on your printer
- Printed on demand just for you, so you get a fresh tool built to your specs
- Grips standard hex bits securely, so your bits stay in place under load while you build
- Compact design fits in your workshop pocket or toolbox, so it travels with you to every build session
Build your RepRap or Prusa printer without switching tools back and forth. This single holder takes your hex bits and includes an M8 nut wrench right in the center, so you handle most fastening jobs with one tool in your hand.
The RepKey is designed by makers who know what you need at the workbench. It holds standard hex bits tight and handles real load during assembly. How strong it stays depends on how well your print comes out, so dial in your printer settings for best results.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
