Nylint Backhoe Treads

thingiverse

Many thanks to @Bustenchops for the original file. Bonus Exhaust (print X2) included. I was looking for replacement tracks for my 1960's Nylint Backhoe and found this model by Bustenchops for the later Tonka excavator. There isn't much information on the rubber parts for these mid-century toys but I took a chance and printed it out. The diameter of the track was good but the center alignment tabs are too wide. In Cura I lowered the Z height to 20mm (the width of the bogies) and the track fits perfectly. The track should probably be 25mm wide at the growsers to appear more scale but that's another day. Print this using TPU or something flexible. Retraction OFF. Print Slowly (<25mm/s) Cooling fan low or off, your choice. Printed OK without supports.
