Card box with separators (e.g. for Marvel Champions)

When I started playing I thought the best way to store my cards would be to use the expansion boxes and sort them in there. I found a 3D-printed insert that looked similar to the two inserts inside my box (can't find the original source anymore, doesn't seem to be on Printables anymore?).

After I noticed some of my expansion boxes getting a bit beat up I planned to get similar boxes to reuse my already printed inserts. When I couldn't find boxes I liked, I tried my hand at designing my own. The result is this box I printed on my Prusa Mk3S+. The inside is as big as the expansion boxes, so any insert for those fits. I also modified the original inserts to have more slots for separators and added slots at the start and at the end so you could put a separator there (just for better sorting).

Then as a last step I designed my own separators because the ones that came with the original insert where not what I was looking for (lightweight and with space at the top to put text).

I uploaded all the files without text like "Aggression" or "Resource" etc. on the separators. Check the photos for inspiration! You may need to mirror the fixed separators depending on which side you want to use them.

Check which TOP part you need - I added a blank one and a Marvel Champions one.

Following advice on Reddit I also added a watermark with just my name - just to prevent someone selling these on Etsy. Open to feedback if the watermark is way too big, wasn't sure how much is enough to make it noticeable to unethical sellers.
