It is a device that allows continuous mixing of various liquids, I use it for mixing sodium persulfate, for etching PCBs, but there are probably other applications, I will not provide assembly instructions, because everything connects logically, and everything is visible in the photos.
things needed:
-printouts
-8x copper thread M3
-2x 625zz bearings (drive the copper thread inside)
-1x 623zz bearing
-12x screws M3x6 (countersunk head)
-4x M3x10 screws
-2x screws M3x22-25
-4X sachets M2.5x8
-6x M3 washers
-2x M3 nuts (I recommend self-locking)
- 4xAA battery compartment
-potentiometer (I recommend 5K)
-switch (any)
-PCB 70x30 (gerber/json/pdf files on cults3d.com)
-connecting cables
This project took me a lot of time, but I publish the basic files for free, but if you appreciate my work and want to receive additional files (.step + .json + .gerber + .pdf + container.stl), please visit my profile on cuts:
