Well this is actually v3 of the design. The angled support makes these really sturdy and they can take a some weight even.
You can easily extend these for your purposes and can be very versatile
If you don't use a heated bed you will definitely get some curling.
I have stacked them on top of each other so the top one is curl/warp proof.
Definitely print with supports, rafts and wave-bonding if possible.
Printed with (and fits in) the M3D Micro
