Red Dot Finderscope Adapter for a Celestron NexStar 8

I recently purchased an older Celestron NexStar 8 OTA and wanted to use the red dot finderscope from my Celestron NexStar 6SE. Unfortunately, the dovetail bracket for the finderscope doesn't align with the mounting holes on the NexStar 8. So, I created this bracket in OpenSCAD and it allows you to use your NexStar 6SE's finderscope on a NexStar 8.
