This is my attempt at reverse engineering the combination lock created by UGears for their wood safe (https://ugearsmodels.com/safe.html).

I assumed their 4mm laser-cut plywood (or MDF), but a simple proportional resize of the DXF will adjust the plans to other thicknesses.

As I drew all components using only intuition and visual acumen, the code wheels and front dial need reworking in order to replicate the code tables displayed in the manual.

It should be fairly functional by now but as I don't have access to a laser cutter in the next few months in order to test it, I will leave it as it is so anybody can rework and integrate it on their projects.

As an assembly guide and visual aid you can Google for the official UGears' user guide PDF.
