Stand for Comsol DCC120 USBC/A Power Supply

I have a Comsol DCC120 USB C & A power supply when I travel on business.  It runs my laptop and charges phones etc - a very handy bit of kit.  It was supplied with a stand that I promptly lost.  

Here's a replacement stand that will allow the power supply to remain vertical and run cooler.  I've designed it with a loose fit so that it's easy to assemble/disassemble whilst moving from site to site.  It disassembles to three flat bits that take next to no room in my laptop bag.

I printed mine out of PETG - as the power supply can get ‘warmish’ if it's working hard.

No supports are required.  15% infill should be plenty as would two or three perimeters.

There is one spine piece.  You will obviously have to print two of the cradle pieces (identical).

Edit:  Have added the STEP file from OnShape for those would like to play with it.
