For those of you that are building a overhead/AFT overhead or pedestal and don't know how to mount them?
I found a L and T rails (with support brackets) so you can print them ;-)
You can use DZUS fasteners (or just m3 nuts and bolds). Im currently busy printing them for myself. I found them on thingiverse.com......here is the link: https://www.thingiverse.com/thing:5149448/files GOOD LUCK !!!
