Business Card Case with integrated clamp

I was looking for a simple yet functional business card case for... my business cards.
Most of the existing ones unfortunately don't have any information about the size the cards may have.
So I designed my own case and additionally gave it some "magic".
Inside of the case is a clamp that holds the cards in place. (In my case it even works with only one card left).

The current models offers place for about 15 cards, depending on the paper quality.
I have also added a slim version for each size (for about 5 cards).

Not to make the same mistake I have included models for various card sizes.
If you are missing a specific size, or want a thicker/narrower design - feel free to contact me.

Available card sizes:
85 x 55 mm - TESTED
90 x 55 mm - NOT TESTED
90 x 50 mm - NOT TESTED
3.5 x 2 inch - TESTED (89 x 51 mm)
65 x 65 mm - NOT TESTED

I would appreciate to see your makes and responses - especially to the not yet tested sizes.

Material

I recommend using PETG!
PLA will also work in the beginning but will not safely hold fewer cards when the clamp is bent over a long time.

Print Settings

There are no additional supports needed when printing as proposed.

The model has built-in supports that can be removed easily after the print (I have used a flat screwdriver). You can see them in the pictures.

You can use Brim/Raft if you have problems with warping.

Wall thickness is 1,6 mm. So your slicer should create 4 wall lines with a 0,4 mm nozzle.
The clamp is a bit thinner with 0,6 mm.

Print time approx. 1,5 h (@ 60 mm/s)
