I have x-acto #11 blades and the tolerance on the slots is much too tight, I can't get them to fit even with a bit of cleanup. The base of the slot looks like it needs to be wider
edit: printed the updated version and my blades now fit nice and snug
I don't know why with some brands of blades the gap is so narrow. I have just updated all the profiles and the design to accept larger blades. Can you print it again? Now maybe you need a drop of instant glue in the base of the blade. Thank you so much.
Print itswlf is good, but I have probablly different blade. It make space between blade and model in blue circle. The space cause paper to jam and not been cut. Try find another.
