Turbine dremel vacuum powered

thingiverse

easy to print little support. if you want to work without dust, this machine is ideal. You connect it to a vacuum cleaner to run it, the outside of the connecting part is 30mm. the disadvantage is that it wears out quickly ( it probaly only lasts for a few hours) ( but it is easy to print a new part ) i used silicone grease for lubrication. It would be better to put a metal sleeve in the rotor, then it would last longer. If you look on youtube for Editing STL files you can find tutorials how to change the design to put a sleeve in i used a m4 bolt for the axle it has got a 3,17mm holder 1/8 inch to put the tools in https://youtu.be/oveKZepUnlw i printed it in PLA also have a look at my other designs for more interesting things
