Duplo-isch roundtable

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 dup
