I designed those brackets to do the sunroof delete on my 8th Gen Civic Si sedan.
The brackets are made for a 1/8-inch ABS sheet.
There are 3 variations of my design. Front, side, and rear.
All the brackets are designed to use an m5 bolt with rivnut to mount to the body of the car, and an m5 heat insert for the delete panel bolt.
For the rear brackets, I had to cut some aluminum angles and glue them to the roof skin to create the “lip” for the 3d printed brackets to be bolted on.
I haven't tried them yet on track, use the file at your own risk!
I printed them out of PETG, 4 walls, and 15% infill.
