Bowden tube holder for Monoprice Mini Delta printer

thingiverse

This is a handy device for securing the Bowden tube on a Monoprice Mini Delta printer - it might also work with other printers, though. It replaces the fragile blue plastic and brass connector that tends to break all too often. I attached small pieces of 100 grit sandpaper to both sides of this holder's 'jaws' to keep the PTFE tubing from sliding around, and now it holds the tubing firmly in place. Two tiny holes were drilled into the printer's side rail to secure the assembly - the two outer screws on the assembly go all the way through the assembly and through these holes, with nuts and lock washers tightened down for extra security. The other screws simply screw into the plastic to hold the block and base together tightly.
