ThirdHand Upright Cartridge Stand

If you use a t:slim pump, you know how frustrating cartridge fills can be:

• Trying to hold everything steady
• Dealing with stubborn air bubbles
• Wasting time (and sometimes insulin)

The Third Hand Cartridge Stand fixes that.

Designed to Work With Gravity — Not Against It

Most cartridge holders keep everything horizontal.

This one is different.

By holding your cartridge vertically:

• Air bubbles rise naturally
• It's easier to remove air completely
• Fills become smoother and more consistent

No more awkward balancing. No more fighting the process.

It's Basically a Third Hand

• Keeps your cartridge stable while filling
• Frees up both hands for better control
• Makes the process faster and less frustrating

Whether you struggle with dexterity or just want a smoother routine — it makes a difference.
