Micro Water Pump - 21 mm motor housing and alternative impeller design

This is a remix of Functional Micro Water Pump by Arron_mollet22, many thanks to him! It's designed to house a 21mm R140 DC motor or any other motor with a diameter of 21mm and an alternative impeller design which I found to be slightly more effective. I didn't think that this pump would work, well I was wrong. This pump cost me less than 1 € and could replace the high-consumption 10 € pumps I currently use for my IOT projects, even if it was powered by a 1.5V AA battery! The new impeller should theoretically be slightly more powerful than the original design but also a bit more vulnerable to dirt. After some tests, I found out that my design doesn't produce as many bubbles. Download "Remixed_Impeller" for my design. I used a R140 motor which you can get from AliExpress for 0.60 $ - https://bit.ly/2TZPcE8 . I used PETG for its water resistance and its relative flexibility (you may use TPU or else for the gasket). Download and print "Remixed_R140_Housing" if you use a R140 motor or "Remixed_Housing" if you use some other motor (with a diameter of 21 mm). The second file could also work for R140 but the first will make it more stable. You only need support for the Pump_InOut thing.
