Raptor Reloaded knuckle pin

thingiverse

You can also try using a knuckle pin from Raptor Reloaded with a marginally increased gap. Unfortunately, after making four tries printing the default pin on varied settings for an ideal fit (at a 100% size scale), I couldn't obtain a narrow enough compression to get the fastening pin through the holes. Consequently, I enlarged the opening by half a millimeter. When it comes to one full hand, you will need to print two of these pins.
