Robo3D Spoolholder Endcap

The Robo3D comes with a spoolholder, but not an endcap to contain it on the horizontal shaft. This results in the spool being able to walk off the end and crash down. This is a small endcap which is easy and quick to print, and then no more worries about loosing your spool off the holder.

One side has a inset for the 1/4x20 screw.
