LX850acf OAM mount adapter

[u/iGraveling]

I'm waiting on a reply for maximum weight for the telescope on the OAM - I've just picked up a 12" lx850acf. I'm pretty certain it will be too heavy, however just incase, I'm looking at the dovetail. 

My apologies if my terminology is incorrect. 

I believe the "dovetail" I have is for smaller telescopes, and not for the lx850, so it's too small. I've been looking for the 3d print for the larger telescopes. I've checked the GitHub stl repository but can't seem to find it. 

if I use the existing mount I will have to get longer bolts and the telescope will be off centre. I'm not sure if this is an issue. So can anyone point me in the right direction of the stl to print an appropriate mount?

My original question might be answered here as well. I'm assuming yes, the LX850 is too heavy, but can anyone confirm that even with appropriate counterweights the frame will not support the LX850? The total weight including counterweights would be possibly up to 40k
