Bahtinov Masks

I still have a bunch of various sizes up to about 145mm diameter.
These all locate on the inner diameter of whatever at the front of the scope.
So, you need to measure the locating diameter to be able to get the right size.
All 3D printed ABS.
Prices are between $15 and $25, plus postage (of your choice).

Hi Glenn,

Yes, I could, but it would be too expensive because I would have to print it in many pieces and then fuse the pieces together with acetone.
A size like that should be laser cut.

Sorry, human, I don't know.
You need a ruler to measure the inner diameter of the dew shield.
Though, a cheap digital caliper would produce a more accurate measurement.
