Notes on Celestron OAG Dimensions

[Endymion42]

Attached are some notes on the critical dimensions of the Celestron OAG should you decide at some point to make a design for it.

I will not support the Celestron OAG. I added a section to the README that documents OAG compatibility. Thanks!

[Endymion42]

Here's a completed design for the Celestron OAG. If acceptable, would you add it to your project for people who want to print and use it themselves?

Regards,
John

This is great! I see you attached an OpenSCAD file. Let me see if I can import it in FreeCAD. Thanks!

[Endymion42]

OpenSCAD file is a bit messy - this may help:

BaseA is
rotate([180,0,0])
CelestronBaseA();

BaseB is
rotate([180,0,0])
CelestronBaseB();

Cover Plate is
TopCover();

Gear (60 teeth) is
CelestronGear();

Pinion (16 teeth) is
MotorPinion();

I added the files to the GitHub repository, and credited you for this contribution. Thank you!

Notes on printing the Celestron OAG parts.

I used 0.2mm with 15% fill. No supports used on any parts but I do recommend a brim around BaseB as there is a possibility for the print to mess up at the end of the semicircular clamp if you don't.
