This is a reducer bushing that fits inside the Starlink Pipe Adapter (square dish) to reduce the size to your pipe. This makes the pipe adapter much easier to install and much more stable. Several sizes included ranging from 1" to 2-1/4" STL's. I also included the .F3D file so you can simply change the one diameter dimension in the first sketch in Fusion360 to fit any size you need. Depending on your printer/material you may need to scale and/or adjust horizontal/hole expansion for the best fitment.

Sizes Include: 1" 1-1/4" 1-3/8" 1-1/2" 1-5/8" 1-3/4" 1-7/8" 2" 2-1/4"

Custom sizes can be added upon request.
