Card holder/bumper, it fits perfectly and tight around all universal cards. Made WITHOUT SUPPORT. Instead of regular support, you have to take an old card and tape it wit painting tape or tape where the PLA sticks good enough on to. When the print is around layer 6/7 you need to place the taped card carefully on top of the print, this holds the last top layers. When done printing you can carefully remove the taped card by the edges and the bit of wiggling.
