Keystone_INSERT-USB_FRAME-and-PCB

I got several pcbs from AliExpress, they have USB micro jacks and pads to solder a usb cable to. They are 14mm X 15mm,with 3mm mounting holes. I wanted to mount them on a fixture that would snap into keystone holes, the kind RJ-45 jacks snap into.
I eventually modelled a keystone plug, with a solid body. I then modelled a frame that the pcb could attach to, and opened up the plug to accommodate it.
However, it was hard to design it so the board could be screwed on, so I switched to this keystone blank, with a curvy latch, and opened the top so a screwdriver could get in there. I tried to design it so no support would be needed, but my first try, the top edges kept blowing out, so I built them up with triangular sections. That worked, no support should be needed.

Apologies, I must have downloaded the curvy keystone plug blank from someone on Thingiverse, but I can't find the source;
