Picture Frame Figure 8 Backing Clip

thingiverse

Very simple clip for holding the backing board in a picture frame. The clip has two screw holes but you only need one screw set in the frame then you can turn the clip by hand out of the way and remove the backing from the frame. I print these 9 at a time and it only takes about 30 minutes with perimeters at 7 and zero infill this prints solid which is what you want. Over all size is about 10 wide x 18 long and 3mm thick. I suggest you flip the clamp over in your slicer software so the countersink is on top before you generate your gcode.
