Main Part for quick change system for OG Star Tracker

Hi, I am currently in process of building my own OG Star Tracker. I didn't know what I wanted to use for polar alignment so i modified the main part so that i could quickly change laser/polar scope/guide scope without reprinting the main part. The holder is designed with M3 thread. I include f3d file so you can change holder to suit you needs. Printing instructions: #The tolerance is 0.1mm #Use 100% infill to stiffen it up If you like this model please leave a like and comment!
