SME Armboard for Triplanar

You should be able to work up the technics plate, as I said just pay attention to clearing all the screws so you can get the arm base flush (let’s jusy say this is something learned through painful experience!)

Take a look here and they might have something that would help you. They have quite a few mounts. Maybe you could buy a blank and have it drilled for your Triplanar.

@jperry thanks I haven't come across that company. I probably need to do a template in mm and send it to them.

I have not done business with them. It does look like they can provide a mounting plate you could use. 

Did you see this listing?
