So I bought this beautiful little HP multi-meter from eBay, and it works really well with incredible precision (don't know last time it was calibrated, but it doesn't really matter for what I do). Unfortunately, the sliding side panel covering the sockets and holding the fuses in place has been lost.

I created this model from photos (unfortunately only the outside face) and inferred the hidden shapes from what I guess was the functionality. I hope someday I come across a complete one and I can check how close I am to the correct shape.

If someone has a reliable method to print legends on 3D printed panels, I am interested. I tried the toner transfer method using transparencies, and it failed miserably. I added a PDF in the files.
