Peristaltic Pump Ballbearings Springs

thingiverse

my new peristaltic pump project got started when my old iwaki bellows pumps began to fail, so i salvaged the motors and designed a nice add on to make this one work. you will need the same type of geared motor or redesign the motor holder and shaft part to make it compatible. I'm happy to share the fusion file if asked. Silicon hose is 5.6mm OD TWO different types of design exist in this folder, one uses: 3 ballbearings scateboard style, measurements for bearings are 8mm (core), 22mm (outer diameter), and 7mm (width). you will also need two springs size 5 x 20 mm, I'm not sure about the force needed yet. files for this start with 22. the other one uses a 12mm roller with small bearing inside: 4mm core hole, 8mm outher diameter, and 3mm width. you will also need 5 x 20 mm springs, I'll update the force when I get my spring kit. files start with SMALL, not 22. you will also need some nails round 1.8mm cut to 14mm length and 10 sec glue. please post a make if you make this one.
