Higher pressure, higher volume than the [original](https://www.thingiverse.com/thing:3306790) + some minor fixes.
Grease the outer gears on this one.
Differences:
Uses 1 1/4" dowel pins instead of 1"

Need 2 more bearings, any R188 will work since these can be lubed.
Tips and tricks:
Pump is designed with 0.2mm of clearance, so sand off any blobs your printer leaves first.
Press the magnets flush
