Keychains experience harsh mechanical abuse: constant pocket friction, keyring twisting, drop impacts, and shear loads. While simple to print, a poorly oriented keychain will delaminate along the Z-axis within days. OddityLabs keychain models are structurally engineered with reinforced eyelets and stress-relieved radii.
OddityLabs Print Note: Never orient the keyring loop vertically on the build plate. Always lay keychains flat on the print bed so tensile loads pull along the continuous X/Y extrusion lines rather than splitting between Z layers.
Set perimeter walls to at least 4 loops or use 100% concentric infill. This ensures the entire hole and mounting stem consist of solid concentric plastic loops, multiplying tear-out strength by up to 400%.
Metal jump rings and 25mm split rings require a minimum internal diameter of 3.8mm to 4.5mm to swing freely without binding. Our keychains feature pre-calibrated chamfered loops that slide smoothly onto keychains without stress-nicking the plastic.
PETG or PLA+ is ideal. PETG provides the best balance of flexural elasticity, layer adhesion, and UV/heat resistance, ensuring the keychain will not break when sat upon or warped inside a hot pocket.
