Travel Telescope 114 (Old Version)

UPDATED VERSION:

https://www.printables.com/model/1038495-travel-telescope-114mm-updated-version 

(The updated version has many improvements that make it much better and easier to use. I did make it a paid model to help continue this project and new projects, Id highly recommend it for the small price it is. I plan to keep this model up for free but will stop updating it, All updates will now be made on the new link above. Thanks for the initial support to keep this project going!) 

Description:

Telescopes are notoriously hard to travel with and I set out to fix that problem. Introducing the travel telescope that can easily be taken apart to fit in a backpack. No tools required for assembly or disassembly. This is a 114mm aperture 900mm focal length reflector telescope. This is a great beginner telescope to make and a great way to learn how telescopes work. Making this telescope will cost less than buying a new one! Buying the parts kit and printed parts should cost about $100 for the entire telescope. A tripod can be 3D printed using metal extrusions as legs or there are M6 threads to mount on any other tripod (A store bought tripod could be more stable). The OTA includes a dovetail style mount for direct mounting on star trackers (Mounting point shown in last photo)

Change Log:

-Added non-rotating helical focuser

-Increased strength and stability

-Added finderscope mount

-Increased printability

Printing Settings:

No supports

0.6mm nozzle (Others will work)

PETG (Or other strong filaments)

TPU for legs and mirror clips 

(you don't have TPU, you can get away with printing the mirror clips out of anything but you'll need to print something to go over the legs if you use the included tripod so they don't scratch a surface)

(Recommended black for all parts)

(See user manual for more detailed printing instructions)

Hardware Needed:

There are a lot of parts required for assembly. I'm selling a kits (or the assembled Telescope) with the parts needed through an online store I made. This is the cheapest way to buy the hardware as you would be buying way more than you need if you bought them all separately.

If you'd like to see a design change or an added feature please reach out for suggested improvements. 

NEVER LOOK AT THE SUN EVEN WITH SOLAR FILTERS, OPEN TELESCOPE DESINGS SHOULD NEVER BE USED FOR SOLAR OBSERVING!!!
