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

I have a receiver that none of my standard sized crystals seem to work in, but one of the micro crystals did, so I created this adapter to help hold it in place. Based on the specs, it should hold 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).

I have included the Inventor files for easy customization. I ended up printing a larger version as it fit in my receiver and printed better. Be careful with your temperatur
