These are Sideplates for the original Vector Frames Motoseat.
The Plates are getting mounted with Screws form the outside wich makes them look real nice.
The inner Plates have integrated Nut holders for the screws for an easier asselmbly of the parts.
I´ve uploaded all parts by itself and the Small and Big plates combinded with the inner and outer plates.
I´ve printed this with 3D Honeycomb infill
Preparing the Inner Plates
When you have printed the Inner Plates you just need to mount an nut onto an Screw and push it with a little force inside the Nut holders.
