PictureFrame corners for 5mm pictures

thingiverse

I required some picture frames for my astrophotos printed on 5mm thick hard foam plate from CEWE https://cewe-photoworld.com/wall-art/foam-board-prints. These triangular corners make the picture appear as though it's floating off the wall without concealing a significant portion of the image, and with the added advantage of invisible screws or hooks. To assemble them simply, screw the bases into place using 4mm thick countersunk screws and click on the covers. A top tip is to start by securing one bottom corner, then mark the next one while holding the picture in place and utilizing a bubble leveler. After that, move on to the top two corners.
