Chemical Mixer

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 cablesThis 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:https://cults3d.com/en/3d-model/tool/chemical-mixer
