from Cleveland,Ohio USA FIRST Team 1001
We used this to learn how to use the MakerGear printer in the KOP.
We did not succeed with the step files as posted, but got others and printed bird's nests, then set the "filament diameter" control and parts started to look OK. The spring holder slot in the Cap kept breaking off using PLA, so we tried ABS and it still broke off. Raised the extruder temperature to 240 and got a cap that did not break yet. In Creator, "autoconfigure for print quality:high", filament 1.5 mm, ABS and temp of 240 and we have a part that is working.

We recommend these changes: 1. don't countersink the holes and use 4/40 socket head cap screws. Kids round out the phillips easily.
2. move string hole completely into the case instead of on the crack between the case and the cap. The string works down the seam and gets stuck. (or move hole to the cap, or rotate the "half circle" so the seam of the circle is perpendicular to the seam between the cap and case).
