Simple Marble Run Scaffolding

I saw the competition and thought about something simple i could create. Unfortunately i don't have enough time to make a full marble run set, but what i could do was create a basic and simple way for anyone to make their own marble runs. This set consists of 3 shapes. 1. a tube scaffold2. an open scaffold3. an open scaffold with magnet inserts. The magnetic inserts need to be regular 3x6mm round magnets. You use regular filament strips to build your own marble run tracks. I attempted to design in such a way that you do not need any glue to assemble. High Flow PETG worked better than PLA Matte for me, but both work fine. Hope this can allow someone to create a great marble run track. Enjoy!
