Fast Track for DIY RC Excavator

These are functionally equivalent with Professor Boots original tracks but print in only half the time.

I like to create 3D models that follow these criteria:

• Do not require supports – I hate supports
• Print quickly – optimized for 0.4mm nozzle diameter with 2 exterior wall thickness
• Are easy to access for maintenance – I like to upgrade parts, but I hate to disassemble the entire model just to change out one part
• Are chamfered on the bottom layer – this helps those who don't have a perfectly aligned bed and may still have “elephant foot” artifacts
• Do not waste plastic – many designers make part WAY thicker than are required for structural strength.  This just makes the parts bulky and take longer to print.
