Ryobi cordless router circle guide

Circle cutting guide for Ryobi 18v router. Cut the middle piece from ply or other material.
My router base was 90.3mm x 89.7mm and the model is made for exact fit. I recommend checking yours first and resizing if needed.
Can be printed from any material. I've printed base using PLA and adjuster end using ASA. I think any material will do.
