PSU offset stacker
Description
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 flat on the build plate (two short print runs per stack), whereas most designs don't fit my printer at all. Having noted that it's optimised for this particular printer, the design should print fine in filament as well. Would love to see someone test that to confirm. The brackets should fit most power supplies, based on the positioning of the mounting holes along the sides - height separation is fixed at 27mm regardless of the psu thickness, to provide adequate ventilation for the bottom supply. Length offset is set to 16mm to give access to the terminals for the bottom supply. You need to print two each of Left and Right per stack - one bracket for each of the four side mounting points. Overall, the setup will fit nicely into one side of a Boxco 280 x 280 x 150 box, with room for a controller and power breakout and/or maybe a third psu to sit beside it.
