This is a pair of darkening rings for the purpose of preventing light leaks within your optical train. Specifically I made this for my setup of:
ASI294MC Pro → T2-Tilter → 2" ZWO EFW
As ZWO does not provide any fitting darkening rings for this setup, I had to create this myself. The one with the holes is supposed to go between the camera and the EFW. The external diameter is 88mm. The inner diameter is 55mm.
I printed this only 1 layer (0.2mm) in matte black PLA. Your printer should be perfectly set up for the first layer in order for this print to work fine.
