Screw Camera Mount bracket

Based on morganlowe's brilliant Frame Edge Camera mounting device, this one, https://www.thingiverse.com/thing:3223228 , this is a variation of the frame edge mount, beefed up a bit in Tinkercad, so its not as pretty.
Made to accept a real screw, you'll need to thread the hole - drill out to 3.3mm for an M4 bolt or try tapping at M3.5 without - the tapping size for M3.5 is 2.9mm..

BTW that photo is about ten times full size, so its warts an all!
