Vertex K8400 Heated bed SSR-mount

thingiverse

I've upgraded my Velleman Vertex K8400's heating system with a brand new AC heated bed. To make it happen, I designed a custom mount for the required SSR (Fotek SSR-25DA or equivalent). It took some effort to get everything right. To build the mount, I used 6 x M3 screws, 10 x M3 nuts (with 4 of them serving as spacers between the bottom plate of my K8400 and the SSR mount), and 6 x M3 knurled brass inserts (each 3 mm in height). The inserts were a crucial part of this project. I added chamfers to the model to make it easier to align the threaded inserts.
