The ongoing Open Labware workshop held at Ibadan, Nigeria had for the first time an “Open Door Day”. On this day, the university community, high school students, the general population as well as representatives from the local industry were invited to visit our lecture hall and talk about 3D printing, open source technologies and the projects participants have been developing! Our aim was to expose people to new ideas and technologies as well as create a welcoming environment to foster local collaborations. We had a very rewarding day, with many visitors and interesting discussions!
