Prusa Mini spring sheet holder with clamping mechanism

I designed this spring sheet hold to eliminate two things that bothered me on the available ones.

First one being the spring sheets not standing upright due to the different thicknesses of smooth, rough and satin sheets.
For that purpose I simply hid some “springs” that clamp on the sheets slightly. (less slightly for the smooth one, since it's twice as thick as the others)

Second thing that bothered me was that I was not being able to properly see which sheet is behind the first one, so I simply raised them by 10mm each.

I printed it out of PETG for the flexibility and because it's softer than PLA.
With PLA I would be worried about the plates getting scratched after a while.

I have been using my PETG version for a couple weeks now and can't see any scratches so I can finally post it with good conscience.
