Magnetic pen holder

##About the design

we had bought a whiteboard but no pen holder was provided with it. So i decided to make a magnetic one. Bonus point if it can be customisable.


## Features

Customise number of pens, pens diameter, magnets height and magnets diameter.

## How to assemble

Get some magnets and some pens. Put the magnets in the holes of the back, put the pens in the hole on the top and put the holder against a metallic surface. Done !

## Limits

Because of some laziness, hole to receive pens are limited to 13mm in diameters and 4 holes maximum are made for magnets. So if you need a 20 pen holder with 8 magnets, maybe you will need to fiddle with the code.
