Summary

My kids wanted a turntable large enough for trains with their tenders, so created this one.
It just about fits on a Creality K1 bed (non-max), which is 220x220mm. All connectors are female, so would require "dog-bone" connectors as desired; any should work. Something like: https://www.thingiverse.com/thing:4672882

Files are:
.stl - Files for slicing/printing
.f3d - Fusion360 design file to modify as you see fit
*.step - Step file for printing or editing
