A small tool to remove or insert the most common type of male luer lock caps. The shaft in the middle makes the cap stay on the tool. The harder you push the cap in, the harder it will stick to the tool.

At the other end there is a M4 thread.

Edit 2019-05-19:
Re-shaped the tool to be 10-sided instead of completly round. Prevents it from rolling away when laid down. Also removed the middle pin as it always broke off anyway.
Download v3 to get the new shape.

I suggest you print this using a Brim.
