Hello!
This is a relatively big (140x110x55 mm) 3-D printed peristaltic pump. It can be powerd by your cordless drill.
There are five parts to print and a few other materials needed
(please see the instructions)
Alterations and suggestions to improve it are very welcome, have fun!

As mentioned in the description, you will need these materials (apart from the five prints):
> 5x 608 bearings
3x M8 bolts (20mm long)
1x M8 bolt (80mm long)
4x M5 bolts (50 mm long)
2x M5 bolts (25mm long)
6x M5 nuts
10x M5 washers
hose: something around 6 mm in outer diameter
The assembly of the pump is showed in the pictures, not depicted in the images are the four M5 bolts that hold everything together.
Note: The pump case may need a little bit of support material, since there are four bigger holes at the bottom. The rest is planned to print without support material.
Detailed information concerning the hose: There is about 2 mm space between the bearings of the rotor and the case wall.
