I posted this model to solve a small problem. 

Metal oil is essential for motor maintenance. After a while, metal oil will leak on the maintenance table or in the toolbox.

But you don't have to worry anymore. 

This holder will not allow leakage on the table or in the toolbox. 

For friends who enjoy Mini 4WD together.

I used the Bamboo Labs A1 mini.
 

<Caution>

This holder is for Tamiya item number "53508" only.
