No Empty Slots: A Custom Vial Case Sized to Exactly What You Carry

September 27, 2026  ·  by VialCase
Custom 3D-printed vial cases in Black, RGB Metallic and Galaxy Blue

Exact fit

No empty slots. No loose vials.

Most cases come in round numbers. Your kit probably doesn’t. Build a case with exactly the slots you need — from a single slot to a clinic-size case, 3 mL or 10 mL, in any mix.

The problem with fixed layouts

A 10-slot case holding six vials leaves four empty pockets and a bigger case than you need. A case that is one slot short means a vial riding loose in your bag. Either way you are working around the case instead of the case working for you.

Build the count you actually carry

In the builder you set the 3 mL and 10 mL counts separately with simple plus and minus buttons. The layout packs them as tightly as our shelf cases do, so the case stays compact.

Mixed sizes, level tops

When you mix 3 mL and 10 mL vials, the 3 mL pockets are raised so every vial top sits at the same height. The lid closes evenly and nothing presses on the shorter vials.

What you can choose

3 mL slots

17.5 mm pockets

For standard 3 mL vials up to 40 mm tall, including the cap.

10 mL slots

26 mm pockets

For 10 mL vials up to 55 mm tall. Mix both sizes in one case — the 3 mL pockets rise so every top lines up.

Storage bay

Optional

Add up to eight open bays for supplies like syringes or prep pads — pick a preset or enter your own size.

Latch & colour

Dual latch on cases 154 mm (6.1 in) and wider.

Frequently asked questions

Can I mix 3 mL and 10 mL vials in one case?

Yes. Set any number of each. The 3 mL pockets are raised so all the vial tops line up.

How many vials can a custom case hold?

From a single slot up to 120 3 mL or 60 10 mL slots, as long as the case fits our print bed. The builder shows the exact size for every combination before you order.

Do I pay for empty slots?

No. You choose the exact count, and the price is based on the size of the case you build.
