I designed thi8s as my first foray into 3D modelling for a friend. He has an Off Axis Guider and did not want to use the prism. He needed the hole covered that the prism installed into. So I designed this in matte black. Since I am not a CAD expert, I could not get the corners rounded and had to use a file to get them rounded down enough to fit into the hole. Feel free to redesign if you have to. The hole in the OAG measures 1"L X 0.5"W. I printed it in PETG with standard settings since I am a newbie and afraid to change settings at this time. LOL
