This thing is a mic clip designed specifically for the Electro-Voice 635A XLR microphone. I imagine it'll work with other mics with 20mm bodies though.
The 8th image (the Cura screenshot) is my recommended orientation for the best results.
Additional Hardware & Fitting
The mount for the clip is designed around a 30mm long M5 hex bolt and wingnut. The hole on the clip piece is tight to keep things nice and secure. It's a bit hard to push the bolt through it at first though. You should be able to push it through with your fingers with a little force, but if you run into trouble I recommend forcing it through with a hammer a few times to loosen up the fit.
This thing is remixed from a few things. Two of them are pretty well unrecognizable, because I basically only used them to match standardized fittings, but I used them all the same so the creators are getting credit.
The most identifiable remixed part in this design comes from FrancisReal's "ADJ Pixel Tube Mic Stand Holder". This model was conceptually very nice, but I found it a bit difficult to get a sturdy print out of it. So I turned the loops into a tube that runs the length of the model, thickened the walls, fused the 2 disks the screw goes through into one solid piece and altered the hole to accommodate the M5 bolt.
The mount takes elements of both Corona688's "Microphone Stand" and tmorris9's "GoPro knob long". While Corona688's design is, ya know... a mic stand, I only borrowed the 5/8 threads from the design so the mount would be compatible with pretty much any standard mic stand. I used the negative space in tmorris9's GoPro knob to cut out the holes and hex inset. He got the tolerances right, no sense reinventing the wheel trying to do it myself XD.
Everything was brought together into a functional part using Tinkercad.
