About this 3D model

For a parametric version try https://www.thingiverse.com/thing:3824099 This is a copying ring for the Festool OF 1010 router. I wanted to see if I can save those 10 Euros for the Festool one. Also I wanted one with 20mm outer diameter. Inner diameter 16mm, outer diameter 20mm. The part was designed in Solidworks. Attention: Original Festool copying rings are made from metal, this one is plastic. If you use unauthorized accessories you do it atyour own risk!
