Heat Expansion Insert - holds two tracks

This insert allows you to store two tracks in a single Heat, Pedal to the Metal expansion box, either Heavy Rain or Tunnel Vision, or a future expansion with the same box size. The four pieces of this insert can be printed all four on a single build plate. I had a 0.2mm nozzle installed when printing this, but it should just as easily print with a 0.4 or larger nozzle.

You can keep the weight low by reducing infill, 7% Gyroid seems to work just fine.

If you download the stl, be aware that you will have to print it four times!

I have printed this model myself (twice, I had to adjust a few measurements after the first print), and it fits perfectly in the box, and the tracks fit in the insert just fine too, without too much wiggle room.
