Remix of the Manta V6 open shield. Added .6mm shims at various points to help prevent "stringing" of layer gaps (and avoid slicer errors) from stacking.
Each piece snaps off from the stack by hand. No clippers required.
Try printing a 2x first and see how it goes.
About 10 hr for 8 stack.
UPDATE 11/4/2020: adjusted shim position and added "PLA" emboss.
In PLA:
.3mm layers
3 walls
2 top/bottom
5% infill (maybe even 0%)
75mm/s print speed
