About this design
Version 2 of my supplement keychain, redesigned to be leak resistant. Carry a scoop of pre-workout or creatine to the gym on your keys.
What's new in v2
- No logo, so the design is clean.
- Leak-resistant seals: both caps close onto a 45 degree crush-ring lip that presses 0.15mm into the body for a tight seal.
- Threaded main cap: 0.70mm thread engagement with 0.34mm flank clearance.
- Threaded neck cap: 0.60mm engagement with 0.32mm clearance, on the small pour neck.
- Keyring tab built into the main cap.
- Round-profile threads for smooth turning.
- Prints without supports.
Capacity
- About 18 cm3 inside, which holds roughly 11 to 13g of pre-workout or about 13.5g of creatine (depends on the powder).
Size (from CAD)
- Body: 36.4mm diameter, 42.4mm tall
- Main cap: 41mm diameter, with the keyring tab sticking out to the side
- Assembled height: about 46.7mm
Parts and approximate PETG mass (100% solid from CAD at 1.27 g/cm3; actual use depends on your slicer settings)
- Body: 8.93g
- Main cap with keyring tab: 6.56g
- Neck cap: 2.43g
Optional: for extra sealing, you can add a thin TPU gasket under the main cap. It's not included as a model file.
Looking for the original? v1 (with logo) is still available in my shop. (If you purchased v1, reach out through cults3d messaging from the account you purchased from and you can have v2 for free and any other versions and alterations.)
Personal use only.
Print notes
- Material: PETG for all three parts - Layer height: 0.12 to 0.16mm. Fine layers help the threads and the seal lips. - Walls: 3 to 4 perimeters (helps the seal and the thread strength) - Infill: 20 to 30% - Supports: none - Orientation: as exported (body upright, each cap printed flat on its top face). Check the orientation in the slicer. - Note: because the threads have a round profile, there's a small overhang (about 1.2mm) at each thread root. That's normally fine without supports, but use good part cooling. - Elephant's foot compensation on, so the seal lips and threads aren't swollen at the first layer. - Fit: if the caps are tight, lower the flow slightly or run a die over the threads. Don't sand the 45 degree seal lip.
