Recommended printing on the side (as shown in the pictures) so the layer lines follow gravity and the print won't delaminate. Requires supports in this orientation.
Printed at 1.6mm walls/top/bottom with 30% infill, but you may want to bump it up if you're nervous.
The author remixed this model.
Modified the opening to fit the smaller bulb, modified the overall height, changed the locking mechanism from a “bump” to an indent
