Although prototyping at present, the final result will installed in the enclosure: the layout can be refined on the bench then bolted into the enclosure. The final module will look much tidier than shown.

I draw the design by hand then send to the plastics supplier for machining. Hopefully this pic helps - there is still a bit of superficial waste hanging from some holes, but you can see the tube socket mounts, small holes for post mounting and larger holes for ties and ventilation:

POM is expensive - an indulgence I am not recommending to others - but allows me to more completely meet design objectives. I'm curious about the non-conductive chassis concept, am not a fan of wood (sub)chassis, and wanted a material that is stable, stiff, strong etc. As a bonus, it is easily machined.

Drilled posts are used to keep the number of connections to minimum, eliminate turrets/tags, and allow building in 3-dimensions while providing component support and ventilation.

Cheers,
