The countersink for the pushpin is undersized for any pins I've found. Should be easily repaired when I get a chance to retry. Aaahhh, the terminology gotcha has struck again. After I enlarged the countersink hole I realized that what you call push pins I've always called thumb tacks. The commonly available US 'push pin' you find in office supply has a much taller head, designed to facilitate easier insertion / removal from cork boards, etc. Not as conducive to the low profile intended by this, but they seem to work fine as well. I've adjusted my rating to reflect by newly acquired understanding. :)

Love this guy. I do wish the cable slot in the back was rotated to match my Alexa though. Fortunately I don't use the AUX port so it works anyway, but maybe a round hole instead to deal with different generational differences would be better.

Way quicker than dealing with the filament transfer via other adapters. My AMS doesn't seem to like cardboard spools due to the edges so this is a great solution.

Snapped into place first try. Simple solution, well implemented. What more can you ask?
