Description

It's a loose fit resting on nubs rather than being screwed in.

Option of blank or decorated lid. Printing the text on the lid requires a 0.2mm nozzle. If you don't want text/decoration, import the lid but don't tell your slicer to separate the features - if you print without requesting any different treatment then it should just print cleanly as-is.

I printed in PETG - PLA will probably work fine, but I don't know how well the snap-fits will hold up to repeat removal.

Model origin

Differences of the remix compared to the original

The original didn't fit the actual board. The screw holes were in the wrong position, not matching the PCB, the screw holes were too large in several places - clashing with the header underside, it was hard to get the lid off without breaking the snap-fits, and the edge-connector cuts on the top were much larger than the . This was measured around the actual board schematics and completely remodelled from scratch.
