ETX70 rear threads to 1.25 eyepiece

Original by by Spotmatic

This allows one to bypass the mirror and use of a 1.25" eyepiece.

I suggest using a #8 or #10 bolt or possibly M5 or M6 bolt to hold eyepiece. I intentionally made this hole large to allow for nuts and bolts that can be 3d printed as an option.

Nut pocket is 4.42mm deep and 11.8mm at the widest, should accomodate many common nut sizes.

100% infill for strength recommended.
