In nearly three decades as an industrial designer, Eric Strebel has amassed a good amount of prototyping tools and skills. Here he employs those tools and shows you his design process, from start to finish, as he retrofits a Letrajet Air Marker to accept markers from other major brands.

Next up, he uses the air marker to help him render what appears to be a Bluetooth speaker and lamp that can wirelessly charge your phone:
