After seeing MarkBensons amazing design (which should be a standard for printing with PLA!) I decided to remove the requirement for additional vitamins (fixings)!
Design allows easily removable 120mm fans to be fitted to the RepRapPro Huxley frame. These can then be controlled via your electronics and Slic3r for active cooling whilst printing with PLA. Cooling massively improves print quality whilst printing small parts or bridges.
Simple and minamalistic!
Print a set.
Fit the shorter legs to the bottom of the fan and the longer legs to the top.
Position the fan so that it is clear of the heatbed and clip to frame.
Control fan speed via Slic3r.
Also why stop with 1 fan when you can fit 2!
