This is a Tri-Bahtinov mask that fits 10in Orion Newtonian telescope or any telescope that has a outer diameter close to or less than 290mm.
The pattern was generated by Satoru Takagi's awesome webapp: https://satakagi.github.io/tribahtinovWebApps/Tri-Bahtinov_symmetric.html
The parameter used are:
Focal length: 1000mm
Outer Diameter: 290mm
Inner Diameter: 40mm
StemWidth:SlitWidth = 1:1
Use 3rd order spectrum = disabled
Bahtinov Factor: 150
inW: 10mm
outW: 15mm
Included STL is a 1/3 slice of the whole. You will need to print 3 replicas of it to make a whole. The slice small enough to be printed with a printer like Ender 3.
