Hey Juan thanks for the share..this turned up recently on reddit..its a remix of an Openbuild design with the attempt to make it more rigid..it looks nice if you want to build one with alu profiles but the work area is a little small and i guess its nice for design inspiration :)
by the way, we have our own gitlab server now: gitlab.fabcity.hamburg
the repos that are on the gitlab.com instance now are being exported to our own gitlab instance
