A holder for the printer’s glass cover plate when it is not in use. It hooks under the printer and sits nicely along the side of the printer. The print is in two parts that side together with a dove tail joint in the centre. To tighten up the fit against the printer’s side I have made a TPU shim to sit on top of this holder to make it fit more firmly under the printer, see: https://makerworld.com/en/models/518802#profileId-435122
