Got fed up waiting for someone to sell them for the UK market so I designed my own.
Requires toggle switch and switch cap. Screws can be rotated in the STEP file (please upgrade your models from STL!) if you prefer them all pointing the same way.
First photo is bare anycubic grey, printed flat so the face is glossy. This worked well with white-on-clear label tape for the text.
Second photo is sprayed aerospace grey, matte finish looks much better but haven’t decided how to do the text yet.
The author marked this model as their own original creation.
