Rigidbot spool rod quick change caps

These caps are designed for the Rigidbot (RB1 and RBBig). They replace the stock spool rod holder ends allowing for a quick change method of the spools by lifting the rod out of the channels. By removing the stock plastic inserts from the ends of the spool rod support tubing these caps can snap over the ends. See the pictures for the swap out sequence.

These caps will hold an 8mm rod and will fit over 3/4" or 19mm square tubing

The STL file contains one cap that is Cura scaled and oriented for printing. Print two caps.

The caps will fit snug. There is a slight tapper to the square hole for the tube insert to allow the cap to tighten as you press it down over the tubing. Use calibrated filament to make sure they print as designed.
