Dual Chamber Syringe Disposal Container

Dual-Chamber Sharps & Syringe Disposal Container (Threaded Lid, Parametric)

Description

Keep your clean and used syringes safely separated in one compact, sealable container. This dual-chamber design splits the interior down the middle with a full-height divider — one side for clean/unused syringes, one side for used/dirty ones — so there's never any cross-contamination.

The used side has its own internal disposal cover with a drop-slot (Press Fit): push a used syringe through the slot and it drops into the dirty chamber, while the cover keeps everything contained. A screw-on threaded lid seals the whole container shut between uses.

Designed for at-home or use while traveling, this container brings a bit of order and safety to managing peptides, insulin, GLP-1s meds, or any routine that involves both fresh and spent syringes.

Printed in PETG for chemical resistance and durability (especially is out in the elements), but PLA works fine too. Everything is fully parametric — use Makerworld parametric editor to resize the container, change the wall thickness, adjust the disposal slot, toggle the divider, or fine-tune every print tolerance.

Please not that depending on material things like the dirty cover might need tolerances adjusted based on material, the profile uploaded was tested with PETG only

Note: This is a personal organization aid, not a medical-grade or puncture-proof sharps container. For final needle disposal, always transfer to an approved sharps container and follow your local regulations.

What You Get

• Body — the dual-chamber container with threaded neck and integrated disposal ledge
• Lid — knurled screw cap
• Cover — drop-in disposal cover for the used chamber

Print Settings

PETG stringing tip: This design has open internal chambers, so if you see fine strings inside, tune your retraction (try 1.5–2 mm), drop nozzle temp ~5–10 °C, and enable "Avoid crossing walls" in your slicer. These clear up almost all interior webbing. (my print profile has this set up)

Assembly & Use

Assembly (one-time):

1. Print all three parts: body, lid, and cover.
2. Clean up any minor stringing inside the neck and on the threads.
3. Drop the cover into the used (dirty) side of the body — it rests on the internal ledge at the 125 mm height. It's a slip-fit; press gently until it seats on the ledge. The disposal slot should sit over the used chamber.
4. Thread the lid onto the body neck to confirm it spins on smoothly. That's it.

Daily use:

1. Unscrew the lid.
2. Take clean syringes from the clean chamber (the open side).
3. After use, drop the spent syringe through the slot in the disposal cover on the used side.
4. Screw the lid back on to seal between uses.
5. When the used side is full, unscrew the lid, lift out the cover, and transfer the contents to an approved sharps container per your local rules.

Customizing (Parametric)

• container_height / container_diameter — overall size
• outer_wall_thickness — wall strength vs. internal volume
• include_divider / divider_height — toggle or shorten the center divider
• thread_clearance — loosen/tighten the lid fit
• cover_curve_clearance — loosen/tighten the disposal cover fit
• slot_length / slot_width — resize the disposal slot for your syringe size
• lid_knurl / body_knurl — grip texture toggles

Happy printing and hope you can find it useful, i wanted something i could travel with and not have to worry about disposal of syringes.
