Ultimaker 2+ PTFE coupler fix 1.75mm

thingiverse

I recently purchased a printhead for 1.75 millimeters and the seller shipped one with defective PTFE connectors. Unfortunately, they didn't offer any solution to this problem. Their response was a simple apology and a 5 euro refund. UPDATE: I designed an entirely new Tube holder that eliminates the need for a faulty coupler. When I encountered issues with the coupler losing its hold on the tube completely, I created this custom replacement. Required materials: Four M3 bolts Four M3 nuts
