This article is very useful for greasing the chain of your motorcycle.
With this tool, you can grease the chain very easily and without the risk of dirtying the entire motorcycle with grease, just insert the straw into the hole, turn the wheel and complete the greasing.
 

The object is divided into two parts, I added 8 magnets to hold the two pieces together.
On the outside there is a hole where the grease straw is inserted.
 

The measurements of the magnets are 10*5*2 mm

You can find the magnets on the bambulab website:

This project was inspired by an existing one on thithingiverse,
