Mixers for 8mm screw rod

thingiverse

I developed these models to thoroughly evaluate the various types of mixing heads. All three have roughly equivalent diameters and can be attached to an 8mm screw rod that can be inserted into a drill. The holes were designed with a 8.2mm diameter for printer tolerances. To scale up or down: Scale the rod to 0.625 if it's 5.125mm, or to 0.75 if it's 6.15mm.
