Centrifuge attachment

Centrifuge attachment by dgs5101 Oct 10, 2011

Description

hold strips of 8 or fewer small tubes and 2 large tubes

i took this design from a pre made attachment that is made of a material very similar to the strength and properties of PLA. As far as thickness goes i took very similar dimensions on the parts of the model that matter. I altered hole sizes and added the slots for the two larger tube for certain needs in an anthropology lab. and this model has been printed and tested and is balanced perfectly and attains the correct speed.

Hi,
I made one myself to spin down PCR mixes. I've used a motor from an old computer fan - the speed is high enough for my purpose. I had to make an adapter to join the rotor with the fan and the whole thing it works excellent. Thanks a lot for this project.

I am currently using a Maker Gear Prusa-Mendel, printing with ABS. And have had lots of luck with this piece. It is a very sound design to print.

What printer did you use to make the attachment?

Instructions

print then drill out holes, use an m3 to screw on to centrifuge base

if it sits too high on the base and does not allow base to spin. just drill the base hole on the bottom deeper and it will sit lower giving you more clearance. I left a good amount of thickness to adapt to different base heights

What sorts of calculations have you done on thickness/material strength, and corresponding speed ratings?
