Just a simple badge holder, nothing more than a smooth edge around your badge. Cards easily slide in from either side and are tightly snapped in place. Model needs supports to print the overhangs that keep the badge in place.
Due to the tight and secure fit, frequent removal might damage the card!
To print the overhangs, I recommend printing high-density supports with increased horizontal expansion. These will easily snap away without damaging the bottom layer. I use the following support settings in Cura:
Z Distance: 0.15mm
X/Y Distance: 0.7mm
Horizontal expansion: 3mm
Resulting supports can be seen in the included picture.
