thingiverse
This is a 90° Diagonal mirror it connects to the telescope with a 2.5" diameter. and fits tightly to a 1.25" eyepiece. I used an 40x60x3 mm optical mirror that I cut to dimensions. This type of mirror can be found in old overhead projectors or found on amazon. Mirror is maintained with double sided tape. Hole size should allow to fit M3*4 screws directly. You can glue the cover for additional support. If not printed in Black, please note that the plastic will let light shine through so it must be painted if you plan to use id during daylight.
