Dovetail base for iOptron CEM40. May work with other mounts, but I haven't tested. Replaces the base that comes with iGuider and allows using any guider scope with the saddle of the CEM40. Should be fixed to the saddle with 2x M3 tapered head screws. For attaching the guide scope, a M4 thumbscrew and M4 nut are required.

Also published is the guide scope ring I use. This is optional, as most guide scopes come with a ring. Mine was very heavy, so this one works better for me. Use with another 2 thumbscrews and M4 nuts. I use with an Angel Eyes guide scope, but should also work with any guider scope with diameter=46mm.

Also added a saddle counterweight bar to be used with 3/4" fender washers. Use a 120mm M8 screw inside the Dec CW screw. Print 2x Dec counterweight nuts and use the washers between them. In my case, 5 washers are enough.
I designed in Blender, so the stl files are very close to the native files.

Can be printed with any applicable layer height. I used 0.3mm and it works fine. Depending on your bed adherence, I advise using a 2-3mm brim.
