My wife is an Occupational Therapist (OT) and Certified Hand Therapist (CHT), and I try to come up with helpful prints for her to provide better care for her patients. All models in this collection are free for non-commercial use. Use in commercial therapy practice is permitted, but selling the models/prints is forbidden.

A key-holed peg board with box and pegs for Occupational Therapists to use for wrist motion exercises. 16 holes on the board in random rotations require the patient to use a variety of different angles. Two different peg shapes are available; one with a stem and one without for different fine motor requirements. Includes FreeCAD project, STL/STEP files, and 3MF files for single (AMS) and split plate prints of flat pegs, stemmed pegs, and both peg types. The 3MF files were generated for a Bambu Lab P2S printer, as that is what I have access to.

**📐 Parameters:**

Most of the measurements are parametric. You can alter the various peg/tab dimensions; the box and board will automatically accommodate the new geometry. This way, you can create wider/longer pegs and tabs to meet the needs of individual patients.

**🖨 Print recommendations:**

- 2 walls, 15% sparse infill, concentric solid infill
- Board color should contrast well against peg color
- Lay the peg board on its top face so the snap-fit tab is facing away from the build plate (already taken care of in provided 3MF files)

**📣 Updates:**

- **v2** - 2026-06-18 - Added hinge and snap-shut features

Occupational Therapy Key Hole Peg Board

Key hole board - Pegboard.stl

Used by Occupational Therapists to loosen scar tissue. Only a single "O" ring tool head is currently included, but I am designing a few more with both broad and acute tips.

**🖨️ Print:**

Recommend printing using high quality settings and PETG filament. Bambu Labs P2S print profile is included in the attachments (since that's all that I have access to). If your printer has trouble with the tops of tool heads with lots of empty space (e.g. the "O" ring tool head), rotate the object so that the flat edge of the bolt is parallel to the build plate. There will be more semi-difficult supports to clean up afterward, but it's much easier for the printer to handle and results in a stronger tool head as a bonus.

**🗃️ Files:**

- FreeCAD designs for handle and tool heads (with blank tool head base)
- STL files for handle and tool heads
- 3MF file for Bambu Labs P2S print profile
