About this 3D model

Heyhooo :) In the past I already designed some windshield defroster for myself. But all went dull very fast and it was a pain to use them with a little amount of frost. So today I thought about a different approach :D What about a milling attatchment for the screwdriver? :P Well it looks a little insane but maybe it works? I don't have snow & frost here in germany atm but if you are reckless enough to test it: Please give a feedback! I have 2 versions for you: 1) Screwed: You can mount the milling part to the axis with a normal 3 mm (wood) screw. 2) Glued: You can glue the 2 pieces together. Printing: I would recommend to use a hard & impact resistant material. But good PLA will do the job I think. Use 4+ Perimeter so the edges have some meat on them! Sharp ice is dedicated to damage plastic :) Have fun! And if it works (or not) give a feedback please!
