Ryobi 18v Trim Router Base Plates

I modeled up some replacement base plates for my 18v Ryobi trim router, I made a square version as well as a round version. Additionally I made versions to fit some template bushings I bought from harbor freight

It may work for other template bushings, here are the dimensions to check:

Hole size dimensions:

Center hole I.D = 1.2 inches

Center hold counterbore O.D = 1.4 inches

Center hole counterbore depth = .1 inches

I printed mine in ABS with 30% infill and .2mm layer height, but I imagine PLA, PETG, ABS, PC, or any reinforced nylons would work just fine as well. Supports are not required for the non-template bushing versions, however the template bushing versions will need supports for the center counterbore. Additionally for the square bases I added little pads 1 layer thick at the corners to help fight against warping for materials prone to warping. The intention was for them to be trimmed off after printing.

*UPDATE 2/4/25*

I added 3 new square baseplate sizes, 5" x 5", 5.5" x 5.5", and 6"x6". I also increased the center hole I.D  on these new plates to be 1.75" however these new plates are not compatible with the above mentioned template bushings.

I added 3 new round baseplate sizes, 5" x 5", 5.5" x 5.5", and 6"x6". I also increased the center hole I.D  on these new plates to be 1.75" however these new plates are not compatible with the above mentioned template bushings.
