Chain keeper remix (built in supports)
thingiverse
Remixed the design to have built in supports that are super easy to remove. As in the picture it will come out looking like it's solid but there is just a .4mm (1 nozzle) wide wall to provide a bridge in addition to 8x 3mm x0.4mm "spokes" to provide support for the inner and outer wall of the "roof". Built in 0.2mm air gap at top and bottom of support section. Preview in slicer, it will make sense.
