PULL-FUGE

PULL-FUGE is a manual rubber band powered Centrifuge, sure it takes more time and effort compared to commercial Hi-tech Centrifuges but much cheaper and can function better in hazard conditions.
It's a cheap solution for medical campaigns held in remote areas in underdeveloped or developing countries where no electricity and low budget field hospitals are expected.

Changes made to the "DremelFuge":
1- Swiveled tube slots same like commercial Centrifuges to ensure that the sediment sample won't mix again after stopping spinning.
2- Enlarged the wheel hub diameter to be tight fitted in the spinner top opening and also to ensure that its centric.
3- Narrowed the tube side access in the swivel carriages as after 1st print the tubes kept flying away at high speeds.
4- Made the tubes hole size less by 0.1mm from original diameter to be snug fit.
