40/123 finderscope

let me introduce printable finderscope.

• lens - 40/123mm achromatic  
• eyepiece - 20mm stock celestron (also good with 23mm aspheric) I made aim cross inside eyepiece
• material - cheepest PETG  
• for printing threads i used 0.11 layers other parts - ordinary speeds and settinds
• small parts (like m6 bolts) printed with low speed - 20 mm/s

put .step file in slicer, split for models, place correctly and print (i printed one by one, not all together)

my lens have coma across all field, but it is not a big deal for finder on the other side i can see such dark objects as andromeda and orion nebula. additionaly it is convenient to use green laser through this finder (easier then through the telescope)
