Not bad, nice and easy to print design, but it's missing an option to add magnets directly on the left side of the poop shoot (left when looking at the printer from the back) to better stick to the sheet metal on H2D's back. The central mounting position via spool holder is strong but due to the H2D shaking like mad it's insufficient to only hold the slide it in this position. Sometimes the distance between the poop shoot and the slide increases slightly (not as much that poop will miss the slide but still enough to make it look like a bad design). Unfortunately your license doesn't allow remixing so I can't share my improved mounting here. Update: When I rated this I was new here and I thought I'm rating the model. But since I learned in the meantime I'm rating the print profile here, I changed it to 5* since the print was flawless (even the model itself has its flaws).
