micro marble track compatible

a lego-compatible micro-marble-track construction system :-)

designed for small **ball-bearings**, with a diameter less than 6mm = the track diameter.
for **best results** look for ones with **4.8mm diameter** - the lego-stud diameter :-)

(standard 608 bearings contain some which are slightly smaller, but still in the right ballpark - got any unused fidget-spinners around?)

Notes:
- designed to print without any supports - might need a brim for bed-adhesion, since the bottom faces have not a lot of area to them - the "notch" in the bottom cavity that connects to the lego-studs should help align the bridges which will form the ceiling
