Replacement endcap for playmarkers

These are replacement endcaps for AK interactive's playmarkers in case you lost any. You could also use them as swatches to indicate the markers color by painting them. The endcap should prevent the button on the back from being pressed so that paint doesn't leak by accident. I've tested the print in both PLA and PETG, without supports. The overhang of the top of the cap can sag a little, but in my case it came out functional.
