I ran out of compressed air cans and ran upon a hand held air compressor. The price of the device was close to the current price for a can 6 pack. I decided to risk the purchase, given return guaranteed satisfaction. To my surprise the little device works better than the canned air and comes with a complete set of tools and attachments that make computer clean up a breeze; pun intended.

The device is delivered in a box that does not provide double duty for convenient storage. So, up with FreeCAD and a few minutes on the MK3S and here is a organizer for the complete set.

You may find the device at Newegg: Compressed Air Duster. https://www.printables.com/model/614699-compressed-air-duster-holder
