Design Concept

The Sure-T Steel Cannula Sharps Cap/Cover is designed as a practical solution for securely covering steel cannulas.

After getting many a needle stuck in my finger, as I am attempting to dispose of these cannulas, I decided to devise a safety cap for the steel cannula.

Purpose

This cap/cover is intended for the safe disposal, providing safety by covering sharp ends of cannulas, of used cannulas. It reduces the risk of accidental needle penetration or biological contamination.

WARNING

I DO NOT recommended using it on new cannulas, that will be inserted in the skin, as there is a risk that small particles of plastic could collect at the needle's end and obstruct the flow or cause an infections!

Printing Recommendations

Print at a 0.2mm resolution with sturdy material, PLA is a cost effective option and my preference.

No supports are necessary due to its simple structure.

I recommend using 3 wall loops and 4 to 5 Top shell layers.

This will provide a solid barrier and prevent the needle from breaching the plastic cap.

Assembly Instructions

Simply slide the cap over the cannula for secure coverage.

Fold the adhesive pad over the ends the cap, to further secure it and place it in a suitable sharps container.
