100x Peptide Vial Case (3ml)

This is a 100-slot case for 3ml peptide vials. I modified the original concept to scale it up efficiently while keeping the overall footprint as compact as possible to save space in the fridge or freezer. A custom internal insert was designed to keep all vials secure, upright, and prevent rattling or clinking during handling.

The case uses mechanical hardware for strength and durability, making it well-suited for frequent opening and closing in a refrigerated or frozen environment.

Design Details

- Fits 100 Vials: Designed for standard 3ml peptide vials (17mm diameter) with caps - Hardware Assembly: Uses (6) M3x30 screws - (2) screws for the hinges - (4) screws for the latches - Secure Insert: Custom internal layout keeps all vials upright and evenly spaced - Compact Scaling: Optimized to hold a large number of vials while remaining fridge-friendly - Material: Printed in PLA+, PLA, or PETG. - PLA+/PETG recommended for increased durability and moisture resistance. - Regular PLA is the default profile as a baseline for beginners. - Has an optional seal that can be printed in TPU (not required by any means, just added peace of mind).

Print Settings

- Filament: PETG, PLA+, or PLA (PLA silk not recommended), TPU for the optional seal. - Supports: None used, tree supports can be added if any overhangs didn't print clean. - Walls: 3 (Tolerances aren’t super tight; all mechanisms work smoothly with little friction) - Infill: 15% (Gyroid is my preferred)

Assembly

Once printing is complete, align the lid and base at the hinge points and secure them using two M3x30 screws. Install the remaining four M3x30 screws into the latch mechanisms. Finally, press the insert into place—it's designed to be a tight fit so it stays locked in position during use.
