Dremel turbine (remix)

thingiverse

I printed Landru's design for the Dremel turbine and I was genuinely impressed with the end result. However, I did encounter some drawbacks that I've since addressed in this remix. To begin with, the small circles that came into contact with each other were a letdown. They all broke off the first time I used it, necessitating removal from my Dremel 3000. Furthermore, the fact that it required screwing together every time was not impressive to me, so I designed an entirely new way of mounting with a very simple yet hopefully reliable latch mechanism. Now, you simply need to press the pieces together and twist - it's that straightforward! I also felt that the short tube was inadequate, so I enlarged it to protrude right to the edge of the turbine. The fit of the impeller was excessively tight for me, leading to three impellers being broken in the process. To address this issue, I enlarged the hole by 0.1mm and ensured correct mirroring. All you need to do is slice it. Additionally, I exported all the files in high resolution to achieve a nicer finish. That's about it. When I have some free time, I'll print it and post pictures, but if anyone prints it first, I'd love to see your results. Enjoy! EDIT 7th May 2019: I've finally got around to printing this design and the first thing I did was that I broke the little latches... They were too weak. The tolerances weren't sufficient, resulting in parts needing a lot of sanding to fit properly. I also screwed the impeller on sideways. But after breaking the latches, everything still snapped together well despite those tiny bits being missing. So, I decided to redo everything. I created a new body and a new mount with hopefully better tolerances (0.6mm) and I also redid the impeller. Now it features an M7 Dremel nut opening and allows you to screw the nut on and glue the impeller straight to it with epoxy. The fit is a bit loose but after gluing everything feels sturdy and the impeller is simple to attach and reattach. The lid now snaps together well, eliminating any fear of those circles breaking away.
