We’ve got help. Meet Oscar!

December 16, 2022 December 16, 2022

As the Holidays are almost around the corner we wanted to decorate our offices. It comes in handy when you have a 3D printer ready to work!
Meet Oscar: one of our GBC designers but most of the times he just observes what’s going on.

Below a picture of Oscar checking a new mechanism for our upcoming GBC of the LEGO 42128 Tow Truck.
