RC Crystal UM-5 to HC-50/U adapter

thingiverse

I have a receiver that none of my standard-sized crystals seem to work in, but one of the micro-crystals did, so I designed an adapter to hold it firmly in place. Based on the specs, this adapter should accommodate either a UM-1, UM-4 or UM-5 (6.9mm x 2.2mm x 6+-2mm). The standard slot is for a HC-49/U or HC-50/U (10mm x 3.8mm x 13 mm) crystal. I've included the Inventor files to make it easy for you to customize the design. I ended up printing a larger version as it fit perfectly in my receiver and printed better. Be cautious with your temperature, as the walls are pretty thin and extreme temperatures can result in holes. The photo is from the standard-sized version and shows a few holes, but that's okay because all it needs to do is stabilize the crystal.
