Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator Z18 Rafts: No Supports: No Resolution: 0.20mm layer height or less Infill: 50% or more Notes: If you like the mesh structure than disable option bottom solid fill. Rotate the model before printing to be horizontally aligned. I printed it in PLA . There are 2 files. Cover with 0.5 mm "removal protector" holds less and its easier to remove. Cover with 1 mm "removal protector" holds much stronger.
