Midwest Gadgets 13.56MHz Field Detector Holder

IMPORTANT: You might need to uniformly scale this in slicer to 31mm on the X axis (other info below). I am new and suck at this, so I don't know how to make it right upfront. :)

Conveniently carry your 13.56MHz field detector without fear of losing it!

This is a case/holder with key ring for the Midwest Gadgets 13.56mhz Field Detectors (28mm) or Smallest Flex 13.56mhz Repeater V3. Best use case is probably the detector though since you don't need to remove it from the case to use it. It is press fit, and since the product you get from Midwest Gadgets looks like it's manufactured in sheets that are snapped off at the right angles, your field detector or repeater will have slightly squared edges protruding from the remaining PCB material that connected the bulk sheets. Use this to your advantage by filing them down just slightly for a perfect press fit into this case. Remember, test the fit, file as needed just a tiny bit, then test again till its perfect. Take your time. I tested it extensively, and it does not come out by accident, but if you do want to remove it, there is a 1 cm hole in the back you can use to press it back out with your finger. Easy peasy! Also, if you're not convinced that the press fit will suffice, you can always put a dab of glue on the back before pressing it in or even hot glue on the outside edge to secure it. The size of the key ring hole should be big enough for most key rings and lanyard carabiners, but measure what you want to use it with first if you're not sure. Dimensions are listed below.

Finally, the detector LED is still exposed, so be aware of that. This isn't for ruggedizing your detector, it's just for convenient carry.

Dimensions:

Outer Diameter - 31mm
Inner Diameter - 28mm
Rear push hole diameter - 10mm
Key ring opening at widest point - 5mm

IMPORTANT NOTE (again): If you're using the STL file, you'll probably need to uniformly scale it on the X axis to 31mm to make it the right size in your slicer. I'm new to this, so forgive me if there are any issues.
