Bare Bones 106mm Dead Cat 'Toothpick'.

thingiverse

I've got a few versions of this design. And will try and get around to uploading some of the better ones. There's a low profile version as well as the standard canopy style, there's indi style and 16x16 mounting pasterns, and there's different motor options... I'm going to include the F3D, so you all can mess with it if desired. I've printed the above frame for 1103 (Racerstar) in Epa CF/Nylon with a 0.4mm nozzle, 0.49 line width, 0.2 layer height 2 walls and 30% infill. And plan to print another in ABS with a 0.3mm nozzle and 3 walls. It's designed to be printed 'Upside down', with the motor mounting surfaces to the heat bed, and no support.
