Summary

Makes a manifold I use for distributing nitrogen gas around a leaky o-ring. Polyflow tube is glue into inlet, N2 comes out through holes. Default parameters generate sections that fit on a Makerbot Thing-o-matic.

Instructions

Usage:
Print STLs directly
OR
Modify parameters at top of to adjust number of holes, sizes, length of sections, etc.
Generate models using functions at bottom of file:
manifold() - To make single section manifold
view() - To view empty area inside the block
left_manifold() - To make three section manifold (1 left, N center, 1 right)
center_manifold() - To make three section manifold (1 left, N center, 1 right)
right_manifold() - To make three section manifold (1 left, N center, 1 right)

Also, I hade to rotate the STL orientation to get rid of overhangs, etc.
