A clamp that holds the Dry Boxes in place on the top of the Lack Enclosure when you lift the lid to service the printer. Used in conjunction with the trays [https://www.prusaprinters.org/prints/45545-drybox-tray](https://www.prusaprinters.org/prints/45545-drybox-tray)) other wise they still slide off :)

Print instructions

I printed these at 0.2mm on a 4mm nozzle. Use whatever material you like. I used PETG but only because that seems to have become my material of choice.
