About this 3D model

The top part of the print-head of my Ultimaker 2 did break (probably I over-tightened the thumb-screws). Here is a replacement-part, which I designed with Fusion 360. The slightly different design is probably more robust than the original. I recommend to print it with PETG (or ABS), no supports needed. I have successfully printed it with Makerbot Replicator and Ultimaker.
