About this 3D model

Optimized for ease of printing and assembly. The main body prints in one piece with supports to clear for the slot for the gates. Gates come in two pieces; the bottom piece can be bolted (m4 bolts) or glued on after you slot it in the gate. Gate slots are sized so a ¼" chisel makes very quick work of cleaning out the supports. Print with snug supports (see pics for what you end up with). PETG or ABS recommended, probably 4+ wall layers for strength. Printed mine with PETG.
