Compatibility

Recommended Print Settings

Since this part is used outdoors and exposed to water, UV light, and temperature changes, material choice matters.

Material (recommended - personal experience):

• ASA — excellent UV and weather resistance (preferred for long-term outdoor use)

Print settings:

• Layer height: 0.2 mm

• Infill: 30–40%

• Walls/perimeters: min. 4

• Supports: needed only on the two places – under two small console mounts

• Orientation: flat side down on the build plate

• Nozzle temperature: per filament manufacturer's recommendation

Assembly

No additional hardware required. The flap simply snaps into place on the accessory box, matching the original mounting points.

Notes

• Test-fit before printing multiple copies — minor tolerance adjustments may be needed depending on your printer's calibration.
