Camera plate for aluminum extrusion 2020

thingiverse

This is a remix of the original file from https://www.thingiverse.com/thing:3446148. I made holes on the base to use the M4 12mm that are used in the open astrotracker build. You will need two M4 T-nuts to attach it to the aluminum extrusion. There are two bases, both have the M4 holes to mount it to the aluminum extrusion, both have threads for 6-32 screws that are very common in North America, the main difference between the bases is that one has a cut-out to insert a 6-32 nut, it's an exact dimension so you may need some force or heating up the nut to fit it, that should keep everything together. The one that I'm currently using it's the one with no nut cut-out and it works remarkably well. The knob has a slot at the top to slide in a 6-32 nut too, you can add a drop or two of super glue so it will stay at the bottom permanently, although that is not necessary. The knob it's this long because I need extra space to turn it to mount/remove the camera, you'll see what I mean when you mount it :p The jaw has a slot where the knob will slide, you align the two holes and then insert the 6-32 screw at the top, start tightening the screw so the thread comes out on the other side of the jaw. The screws that I'm using are 49.66 mm ~ 1 61/64 (1.955) inch long. Before you take this thing outside, make sure you test it, make sure it's tight, and move the DEC wheel on the astrotracker in all possible configurations while you keep a hand or two close the camera in case it comes off. I'm not responsible for any damage that may occur. To print I recommended a minimum of 3 walls, 20-25 infill, 5 - 7 bottoms and tops, using 0.2 layer height. PETG is what I'm using, if you use PLA I'd say a minimum of 4 walls. All the files have been positioned already for printing, no supports are needed.
