Work in progress

Screwdriver stations.

The lettered sampler did its job: letters E, I, M and O became four magnetic holders, sliced and ready for a test print. The sampler remains below for anyone choosing their own letters.

Ready to test print · MH01-MH04 v1

The letters became holders.

Six-seat jeweler bar (E), four-seat 6 mm (I) and 8 mm (M) bars printed in pairs for eight seats, and a wide-pitch 1/4 inch hex bar (O). Seat pitch follows the 25.4 mm grid so bars tile across the 2 mm seam.

Sealed 20 × 10 × 3 mm magnets, same tight pegs as the sampler.

CAD and sliced paths checked. Not yet printed.

Current test print · MS01 v3 recoverable

Test the fit. Keep the magnets.

Same A–P shaft seats, now with open 10.8 × 3.8 mm channels for your 20 × 10 × 3 mm magnets. Load after printing; matching flat-print combs retain all eight magnets with removable tape.

No print pause or permanent caps. Peel the tape and slide the magnets out for the next test.

CAD and sliced paths checked. Physical sliding and magnetic feel await testing. Sealed v2 remains available.
