My version was printed using Orca on a Creality K1C using ABS and 100% infill ( 100% infill as much for strength but also making it more able to withstand a bit of flex which is going to happen on a snare mount).

EDIT: I just made the file as a .stl (Snare_mount_stronger.stl)
All that is needed now is the .stl file

Printing was orientated laying flat with the ‘teeth’ upward.
Support = normal
ABS is what I chose but probably could be PLA or other. I just wanted the strength of ABS
The washer I used Orca ‘primitive’ shape disc, scaled to 25 x 25m x 4mm then added another primitive shape (negative) sphere, scaled 9mm x 9mm x 10mm and positioned it through the center of the disc and also through the plate to get a hole. I have included the .stl for the washer.
The assembly is straight forward
