If you are studying on Ærø, you have access to several practical workshops.
FabLab in Motorfabrikken
FabLab is a number of workshops where prototypes are designed and manufactured. There is access to machinery including a 3D printer and laser cutter. There are workshop evenings on Tuesdays and Thursdays where you can learn how to use the various machines.
In the Youth School you can use the motor workshop and tangle with mopeds or maybe repair your bike or an old lawnmower. You can also take a hunting license or participate in some of the other activities.
