Vacuum Dremel with integrated RPM control

Share Photos of your Copies! This is in Beta state, but it works - better videos are coming soon. High-speed ball bearings are definitely needed. Be welcome to help making some parts more adaptive with a customizer or OpenSCAD - I can't do this myself. Easy maintenance... It's friction fitted onto the Vacuum Turbine thing: http://www.thingiverse.com/thing:76369, also friction fitted to my vacuum tube... (not very stable). Still needs some proper adapters. Maybe an inner-cone in Bendlay... The Turbine is surprisingly strong on a Dyson 1200Watt Vacuum... So I definitely can use this as a tool. I don't leave it to run on maximum speed and load for longer than 30 seconds... just so it doesn't melt away (prototype made in PLA). It heats up quite fast when drilling on harder materials. The grip and the rpm control lever work but there's quite some potential for improvement... like a spring and overall stronger build. Maybe the angle of the grip should be adjustable in a future OpenSCAD version... http://www.youtube.com/watch?v=COdubneKGu0&feature=youtu.be http://www.youtube.com/watch?v=MVtcggWWsRQ Pay attention to which turning direction you need. (The bits can be left or right turning ones...) To change the turning direction, you have to mirror all turbine parts. This way you can build a right- and left-turning one. Keep in mind that OpenSource always should be metric... so ID for the axis in my turbines is 6mm. The turbine blades are held by friction right now... I want to add a fix later. Mirror the Gripthing for completing the part... (glue it together). Drill the holes in the receiver part so bolts glide easily. The whole thing will be made compatible with these Drillbit holders: http://www.ebay.de/itm/1504-Bohrkopf-4-Spannzangen-/300910972343?pt=Elektrowerkzeug_Zubeh%C3%B6r&hash=item460fb10db7 With this way, I can have a smooth rod axis that needs no special machining.
