I downloaded and printed a scraper blade handle, but found that the included blade case was lacking in a few respects.

This case is a lot looser of a fit to the blades and has more than one way to push or lift them out. The tray is designed to only fit the sleeve in one direction to prevent it getting stuck without something to grip to slide it out.

It should fit 5 plastic scraper blades.

Print in the orientation loaded with no supports. I used PET-G but anything should work.

I added another sleeve with an internal pin to hold the drawer closed. The original was a little too free flowing. It's a quick print either way, 23 minutes for the pair or 12 minutes for just the sleeve.
