This is a raw canvas hanger that can be easily attached to the canvas frame with a staple gun. Use ½" or longer staples for a solid connection.

It has a hole for centering the hanger on the canvas and two hanger options.

With these, I was able to hang a lot of canvases quickly. On the Prusa Mini, a plate of 8 takes about 4 hours with petg.

FreeCAD file included.

I'd never heard of the character but I was told it might have a Domo aesthetic, any resemblance to characters living or imagined is purely coincidental.
