Summary

A mount for the T7 Shield with 2 holes (can work with only one if you don't need 2); designed for 1/4" screws but works with anything as long as the screwhead is similar size.

The 2 holes are 25mm apart (on the Tilta cage, if you mount it on the rear 2 screws, you can still access the mic ports).

Printed from TPU (I recommend using flexible materials as it is not tightened any way, only friction is holding the SSD), holds mine nicely (won't slide out, but not too hard to remove), you might need to play around with size depending on your printer's tolerances, or if you want it to be tighter.

Recommended to print with multiple walls (at least 1mm wall width), infill doesn't really matter, neither do layer height.
Excuse my terrible print quality, the random noname TPU I have loves to randomly clog.

Also attached a dummy SSD, made by the original designer KwadLife.
