Very nicely detailed instructable. Thanks for sharing!

Real life problem solving :D

Thank you, that was very flattering!

Thanks!

Great job Stan, quite a lot of work!

Hey, all parts are available on ebay. Just make sure that the specs listed by the seller are genuine.Search 'mini collet', there will be plenty of 3.17mm collets.I too don't like using adhesive, but this was done on a short timeline for the contest and screws for plastics are hard to find. Also, the space constraints and optimizing the design for 3d printing, too many things! Adhesive was the easier option..relatively!

Marco, Thanks for your comment. Have a look at this: https://www.amazon.com/GOCHANGE-Electric-Accessori...Same concept, same type of mounting, probably a cheaper motor. Based on the reviews, It seems to be doing good. The main use for my instructable is for people doing light work on plastics/woods/foam etc not heavy duty metal cutting.As for the economics, if you don't have a 3d printer already, it's going to be expensive. But you get bragging rights in return. As for comparing 3d printing with mass production, there is no contest at all....at the moment. I too was thinking of the durability, low rpm and all, before making this, so I ordered 2 motors one at 6k other at 15k rpm. I chose to go with 6k rpm and am pleasantly surprised. I now use my own rotary tool for most work. Light-weight…

Thank you! Great to know that this can be useful for people.

Thank you very much!

Thanks for your comment, I don't think this will be a good choice for using in CNC. I found this to be good for light work when you need low noise/weight where something like dremel would be an overkill.

Thanks for appreciating, I don't think of using this for a CNC. However, a CNC machine is on my list, hopefully this year I am able to make it!

I have used it on Aluminium and Wood among other materials, nothing has happened so far. I can hold the device upside down from the front cover, and the snap fit doesn't come out either. The 2 casing parts are stuck using adhesive, so some of the strength depends also on the adhesive used.

Thank you for your comment, Glad you like it!

Thank you Ross. Happy to have your vote!
