Print-In-Place Wrench 3D Printed Workshop Tool

Design preview. Rendered from the file, not a photo.
This model is not currently offered as a verified ready to buy print.
What it does
- Moving internal parts print as one piece so you skip assembly and get a working wrench straight from the printer
- Redesigned internal mechanism grips fasteners tight so you can tackle real jobs in your workshop
- ABS material handles shop stress and wear so your tool lasts through tough projects
- Edit the STEP file to customize the wrench for your own needs and experiments
You get a fully working wrench where all the moving parts snap together during printing. No glue. No screws. Just one strong piece that does the job from day one.
This is a reworked design with better internals than the original version. The print is tricky and demands your full attention; it is not a beginner project. You will need patience getting the parts to move freely once it comes off the bed. But it is possible, and when you succeed, you hold a wrench that works.
The creator, Daniel Norée, shares the STEP file so you can tweak the design to fit your vision. Whether you want to change dimensions or test new ideas, you have full control. This tool proves that 3D printing makes functional workshop gear that rivals traditional tools.

What it is made of
Designs like this print well in PLA. Compare the materials.
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 We have not load tested this design, so we do not publish a weight rating.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.
