This is a Face plate for a 19" Rack with separate build plates for both 1U and 2U tall face plates

Assembly is easy

Once you have removed the supports you can just slide the two halves together and use standard 19" rack Screws and washers to fit.

DO NOT over tighten as these are after all printed plastic.

I used PLA because I do not have a lot of heat generated but you could use PETG or ABS if needed.

While gluing is not strictly required using a little cyanoacrylate based glue (not super glue) on the front edge and holding with that edge together will ensure a flush fit ( see cover vs 2nd fitted photo)

I designed this from scratch in FreeCad and could also upload the 3U plate Sizes if someone needs. One side would only (just) fit on a plate
