Qid Xsmart-3 lid riser

These hold the lid on top of the printer while providing some ventilation. There are small retention nubs so they can stay on the printer even if the lid is completely removed.

The 90° parts were printed with 0.20mm layer height, 2 perimeters, 2 top and bottom layers, 25% infill. The 135° parts were printed with 0.12mm layer height to help with overhangs. No need for support. Print them so that the rounded corners are up in the air. I didn't use brims, but you may need to if your bed adhesion isn't dialed in.
