PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
My 200/1000 newton telescope from ABS which weights only 5,5kg
a regular 200x200mm printer is sufficient for the OTA and mount.

Construction designed for the HC-1 focuser which weights only 62grams and don't jamming in the cold which frequently occurs for the threaded helix focusers. (may be used another focuser but this requeres focuser-platform redesign)
the list and the number of printed items in a text file
Also this construction requires a bunch of bolts and nuts, M4 and M5, three good and hard springs (with diameter of M5 bolts), 8 aluminum tubes of diameter 12 mm

In the comments ask a question what kind of mirror will do. Only parabolic not spherical, on Ali Express often sell spherical mirror , it is necessary to clarify this point
I'm not very well versed in trading platforms but I think on eBay you can buy the right mirror =)
I just did - I bought a used tube Newtonian without a mount (OTA) and took out of it :)
I have a set of 203mm primary mirror with a focal length of 1000mm and the secondary mirror 52mm small axis. You can take the 200mm mirror with a large (or smaller) focal length, this will require to add a length…
