This is a remix of the design AdamDC came up with for a full body / shell spinner. His brushless motor friction wheel on a sled concept is awesome!

This is my V2 design and my V1 design exploded whenever I got the shell up to speed. V1 had issues. Two versions of the shell are included. A three toothed wacker and a twisty ramp swirly thing that crossed my mind. Still playing around here.

Also, this is designed to print on a 200mm x 200mm bed size.

Here is a BOM:

Electronics and things I crammed in there: 8mm aluminum Rod Bearing - 608 sized skateboard bearing McMaster #5972k910 C-Clips - McMaster #9853a114 Esc = DasMikro Duel (http://tinyurl.com/ybvkxqxj) or a pair of these EBAY 10a - http://tinyurl.com/y7d8ql88 RX= Hobby King 6 channel to work with the entry level Hobby King HK-T6A Transmitter Drive Motors= N20's 50:1 (though I think 30:1 would be quicker) Weapon Motor= DYS BE1806 2300KV brushless (http://tinyurl.com/y8rayba8) Shell ESC = RaceStar 10a (http://tinyurl.com/yd35e9la) Battery = Nano-tec 3s 450mah Wheels = Lego 35mm + the 3d printed lego hub attached All body screws and hardware are 3mm belly mounted master switch = i use these DPDT from amazon, (http://tinyurl.com/y6v7nf3m)

The teeth were cut from a sheet of 0.5 thick UHMU purchased from McMaster as well.

Happy spinning.
