About this 3D model

i have added a picture of one of my proto types made out of foamboard. a turning disc for your duplo trains or roundtable / roundhouse my 1st try ever i'm still very new to al this and comments are verry welcome and if you want to make i deriative i would be pleased note that these are all sollids (it probably would make more sence to make the parts hollow) and i would like to ad holes on the bottom so duplo bloks fit underneath. and some duplo studs on top to connect duplo there alsow i want to make "pits" and "hills" that would give a *auto allign" to the six positions the turning disc has idealy i would like to see shomething with gears and a turning knob. for now i added a pin you can push for easier turning i hope you LIKE it, and please let me know what you think before i forget its HUGE!, the finished version wouldbe a cut up version, that you can put together after printing why its so big? its 2 duplo tracks long so it will fit nicely in your duplo track design. the long track part is just there because i used it as a tool to create the round table This thing was made with Tinkercad.
