Lower profile 40.5mm filter adapter for OM System TG-7 / Olympus Tough cameras

This is a relatively low profile 40.5mm filter thread adapter for the OM System TG-7 and other Olympus Tough cameras. This lets you use the same filter size as the default Olympus/OM System filter adapter CLA-T01.

I suggest printing the ring parts with the front part down (as it's oriented in the stl) with 0.15mm layer height. They should be fine without supports. 

*⚠ Important notes: 

1. This adapter is designed to be relatively low profile and thus is not compatible with the official conversion lenses (at least not the TCON-T01, I have not tested any others)*. 
    
2. This has only been tested on the TG-7. It should work on other TG series cameras, but I haven't been able to test. 

Post a make or leave a comment if you're able to try it!

*You could probably make a remix which positions the conversion lens the same as the official adapter, but the thing is… Third party adapters are very cheap, so it's probably not worth the effort. 
Just get a random ebay CLA-T01 equivalent if you need to use conversion lenses, and consider this a solution for using 40.5mm filters with a lower profile than the official adapter. 

I used this blender plugin to help get the filter thread right:
