My multistage peristaltic pump ( https://www.thingiverse.com/thing:3181407 ) seems to be good, but after a while, some poeple asked me, to create a switchable pump stage.
So I´ve thougt about it for a long time. After a few month of brainstorming, drawing, testing and a lot of filament, I´m proud to present the first working prototype!
You need a lot of 606zz and 608zz ball bearings, much M3 screws and importantly; GREASE!
The coupling is based of the Hirth-toothing, so it should be good lubricated.
Anytime soon, I will upload of an servo-powered switch.
Everything here could change anytime, because I´m still developing. I will upload always the newest version and delete the older. So be careful, if you want to combine new and old parts.
If you have any questions, ask me and I reply as fast as possible!
