shorter "Enlarged simple wedged tracks - Duplo compatible marble run"

This is a simple remix of this thing: https://www.thingiverse.com/make:725432 I just needed a shorter version but with same hole diameter of 26 mm to fit my delta printer with 200 mm bed. So just scaling was not an option (see "How I Designed This"). The original design is 224 mm long = 14 Duplo studs wide (12 studs between blocks). My 193 mm version is still too big for my printer, so it is untested. It is 12 Duplo studs wide. My 180 mm version is successfully printed. It is 11 Duplo studs wide. My 176 mm version is not tested yet. It is 10 Duplo studs wide. Thanks to the original author and the former remix with bigger hole!
