I designed holder for my laptop power supply to reduce its temperature and not to knock around my feet while sitting at the desk.

I made sure to provide fast removal and insertion of the power supply, you just slide it in or out.

It is designed for Lenovo ideapad laptop, but may also fit other power supplies.

What's more, I added as many holes as possible to provide any air flow (and tried to make it look… not bad).

Dimensions of my desk's legs are 20x20 mm.

I uploaded 3 variations of the idea:

• Original - the one I am using 
• Without hooks
• Only with vertical hoooks

I also uploaded the gcode of the original version I printed some time ago and a step file of the original.

You must be careful not to break anything while removing supports and while using.
