A simple way to stack PCBs, especially while they are waiting to be populated. Works with populated boards too, providing there is a little bit of the edge to hold on to. Design is parametric within Fusion 360 - just change the number of circles on the x and y axis and the rest should take care of itself.
No special printing instructions. I use standard PETG settings within PrusaSlicer, with 20% infill.
The author marked this model as their own original creation.
