I like to build, make and to tinker - since over 40 years. Built my own furniture from scratch, a coffee table with an N train set (built and programmed from scratch), built model airplanes, models, programmed, built hardware, ... The only thing I could never warm up to is nitting and such.

But using a 3D printer is soo much fun!

The first 3 projects I created in my cad program came exactly out as planned. Wooowie!
