PSU offset stacker - old version

*** OBSOLETE ***

This has been moved to https://www.thingiverse.com/thing:5378456. Ran into a glitch in the MakerBot software that means it's only visible in some places. Their recommended solution was to copy it to a new thing.

I need to stack power supplies with controller boxes for my Christmas lights display. There are a number of psu (power supply unit) stackers out there on Thingiverse, but none of them fitted my particular needs and preferences, so I put together a new design.

The controllers I build generally go into Boxco boxes, which come with a base plate and I mount the lower psu onto a base plate via the mounting points on its bottom. So to stack a second supply on top, I only need to interconnect the side mounting supports of the two psu's.

A big restriction for me is that I've also only got a little Anycubic Photon Mono UV resin printer, which has a small build plate area and won't fit most of the existing designs. I can fit a pair of these babies fla
