Newtonian beginner telescope

This is a printable telescope with very few parts that I'm making for my son as a Christmas gift. This is my first attempt to make a telescope, and I am really happy with the result. It works really well. And was easy to build and print. It has 2 different mounts, The telescope_mount is for a old tripod (seben EQ3) Second one is Vixen Style Dovetail.

Update 16.11.2019

I added a new piece to the telescope. Now you can mount a raspberry pi camera directly
on to the telescope instead of mirror end eyepiece. The new parts are:

1. Camera Focus
2. Topp_rpi
3. Rack
4. GT2 Timing Pulley 16 Tooth Bore 5mm (https://www.aliexpress.com/item/32950478691.html?spm=a2g0s.9042311.0.0.27424c4deq9xLw)
5. 5mm Aluminum rod that is at least 100mm long
