Detachable bic pen holder with adaptative pressure for plotting with Geeetech A20M

A detachable pen holder for bic recharges to plot with your Geeetech A20m. The spring prevents problems if you fail to set the z offset accurately and allow a certain degree of freedom in your bed leveling. It also allows to detach and attach the pen in seconds as many times as you want without the need of manipulating the printer every time.
