v4 printed and worn. See the finished build below. v5 has CAD and slicer checks only; its physical fit and magnetic holding remain untested. Print the small fit coupon first.

Same idea. Different loading direction.

v5 / REAR-LOADINGLatest iteration

Clear front. Screw cups behind.

Magnets load from the back in removable threaded cups. The front retaining lip is part of the body, so no cap flange sits on the contact side.

Ring diameter: 28.67 mm
Overall CAD height: 7.00 mm
Magnet bore / tilt: Ø5.30 mm / 15°
Front retaining lip: 0.32 mm nominal thickness

Cleaner contact side, not a thinner overall assembly. The tilted lip’s sliced thickness varies locally.

v4 / FRONT RETAINERSEarlier iteration

Actual v4 CAD render: assembled four-magnet carrier beside an exploded view of its thin front screw retainers — v4 · Assembled and exploded CAD views. Tap to view full size.

Compact body. Thin front caps.

Magnets sit inside threaded retainers that screw into the sockets from the front. The compact revision uses a thin retaining face and wider magnet bores.

Ring diameter: 29.19 mm
Overall CAD height: 6.33 mm
Magnet bore / tilt: Ø5.30 mm / 15°
Cap retaining face: 0.32 mm · two 0.16 mm layers

Use matching body and retainers from one version. v4 front retainers and v5 rear cups are not interchangeable.

Inside both ZIPs

Start small. Check the fit.

Each package includes STL print models, editable STEP CAD, Bambu 3MF projects, Python source, previews and a README with assembly and print notes.

Download and unzip one version. Read its README before choosing a plate.
Print the fit test first. Use OMI_PLA_FIT_TEST.3mf, or reslice models/fit_test_plate.stl for your printer.
Check your magnets and threads. The reference magnets are estimated Ø4 × 3 mm; measure yours. Check retention and polarity before trying the full carrier.
