These tabs are designed for Shadowrun: Crossfire. They allow you to reuse the (in)famous upgrade stickers.

Instead of permanently sticking the upgrade directly to your character card, stick them to one of these tabs instead. They are designed to clip to the character cards, allowing you to easily reassign upgrades without permanently destroying the game.

I've included the OpenSCAD file. Feel free to modify and share your results.

Enjoy!

I managed to print several tabs in one run using Cura's multi printing setting "One at a time"; however the first tabs that were printed would tend to "curl" due to the exposition to heat. I fixed the problem by slightly reducing the bed temperature from 50 C to 45 C.
