Rounded Tetrahedrons
thingiverse
This small item can be easily carried as a keychain or something similar. To prevent it from being stuck in jacket pockets, it should be printed at a size large enough to accommodate a key securely attached. Print Settings Rafts: No Supports: Yes Resolution: 0.2mm layer height is more than sufficient for this design. Infill: 25% is the perfect density to maintain structural integrity without wasting too much material. Notes: A very robust PLA filament was chosen to ensure the printed object can withstand being tossed towards the front door while carrying a key securely attached. How I Designed This Blender was used to create this intricate design.
