Tolerance -

• Circular <18mm diameter - 0.15~0.2mm (ex. 8mm hole → 8.2mm)
• Circular >18mm diameter - 0.2~0.4mm (ex. 26mm hole → 26.4mm)
• Rectangular - 0.1~0.3mm (ex 15x15 hole → 15.2x15.2mm)
• For longer holes, ex. wing sections, give tolerance on the larger side

Infill Consideration -

• Infill interface with hole may result in tighter fit in that section. Consider infill optimized prints (youtube tutorial - Tom Stanton)
• Gyroid and 3D Honeycomb for highest strength/weight ratio
• Infill shape will impact part strength in different axes. Ex. Grid infill will be strong in 90 degree loads, but weaker to 45 degree loads.

Bed Adhesion Consideration -

• Ideally use brims to reduce warping. Even for PLA prints, longer or wider prints, or higher infill density prints will result in warping.
