I sized two frames for the files that I'm building with the kids.
They are friction fit, just put the bottom of your hueforge print into the groove and then push the top of the print into place, and you will hear a “click”. You can remove the print the same way, by applying force to the top edge of the print.
Currently all of my uploads are between 2.24mm and 2.96 and these will work for all of them that are sized in either 150x100 or 100x100 dimensions.
Currently holds:
100x100
100x150 - Updated a print profile so you can use the frame as 100x150 or 150x100 (landscape or portrait)
150x150
I have built a 200x200 Friction Fit Frame as well now

You could resize other hueforge to fit in these as well.
