‼️ Beware! Do not store at extreme negative temperatures. Only for chilled use.

🧠 The first idea came from the design https://rokycany.nemocnicepk.cz/tiskove-zpravy/problem-nestabilnich-vakcin-vyresili-3d-laborator-zapadoceske-univerzity/

🤔 I needed to solve couple of things:
– lack of Moderna version
– weak connection of the hex supporting pillars
– too wide walls between hexagons

1️⃣ I created a separate version for Moderna vials (they are wider at 24.15mm with label) and could not fit into the original design.

2️⃣ Added chamfers on the bottom of the hex windows and changed the top fillet to a chamfer (better overhang performance).

3️⃣ Additionally I changed the distribution of individual hexagons to adhere to each other by exactly one wall width. This decreases the print time as it is exactly 3 perimeters wide.

Print instructions

Print with 0.4 mm nozzle.
Layer height 0.3 mm works great.

Printing in PETG to be a little flexible rather than PLA that might become brittle.
