ER11 Collett Holder (15x)

thingiverse

I created a custom collett holder for my router. It's roughly 4.5 inches by 3.25 inches, made from 1/2-inch MDF, and worked perfectly. The colletts fit snugly in place, so they won't fall out easily. If you want to loosen it up a bit, just hit it with a file. Check the image or DXF for the precise sizes. I can create different versions if people are interested - just post your requests in the comments section. The Solidworks file is included for anyone who has access to the software and wants to make their own modifications.
