Bambu Lab AMS riser feet 10mm

Remix changing the height a little, now 10mm.  Plus a hole for a circular foam pad of 18.5mm diameter (minimum of 3mm deep, or slap multiple in if less).

Enables me to slide a thin heat-mat under the AMS unit.  In my case, a 5W vivarium / lizard tank heatpad, to help with humidity in conjunction with desiccant in the AMS.
