I spent an age looking at all the different poop shute models and this was by far the nicest and most functional design that I found. The only problem that I had was that it rattled around while printing and fell off on a couple of occasions. I modified the original design so that I was able to insert 8 magnets to the back and now it holds on tightly to the back of the printer. Thank you so much for such a carefully designed model. I have uploaded my modified print profile if anyone else is interested in it.

Really nice simple design, it does exactly what it's intended to do and it's quick and easy to print.

Easy to print, great tolerances, everything you need for a really good model.

Printed for a friend of mine. I had never heard of a vocal trainer, but she was very pleased and that's all that counts!
