Holder for 12V to 5V USB Buck Converter

I'm Using Maximpulse's excellent floating LED light (https://www.thingiverse.com/thing:2237352)
for my PRUSA i3 MK2s, I've added a 12v to 5v USB converter that runs off the printer's 12V power supply.

This is a simple holder that mounts onto the side of the power supply by friction to hold the
converter with it's USB socket.

The 12V to 5V USB buck converter costs only £0.99 from China and can be found at:
https://www.ebay.co.uk/sch/i.html?\_from=R40&\_trksid=p2380057.m570.l1313.TR1.TRC0.A0.H0.X12V+buck+converter+USB.TRS0&\_nkw=12V+buck+converter+USB&\_sacat=0

Connecting the converter to the power supply is simple: Unscrew the PS from the printer
(4 screws), unscrew the plastic cover (3 screws), slide the PS out (leaving all wires connected - it will only slide a few inches), and attach wires onto the spare 12VDC +/- terminals -- negative connects to the converter on what I'm calling the "left" side (the side with the led).

The little hole on the left side is to insert a piece of 1.75mm clear filament to highlight the red light (not really necessary but looks good).

UPDATE I've created a new, simplified solution for the nozzle light. It puts the buck converter and USB LED into a single unit. Check out https://www.thingiverse.com/thing:2506110
