Shower Drain - Customizable

Replacement for a broken shower drain.

Inspired on a design from Dave Borghuis
https://www.thingiverse.com/thing:3964077

Adds rounding between the pipe and the lid.
If the holes parameter is undefined or not specified a sensible default is calculated

Tried and tested in the field for more than 4 years
Customize as needed.

Have fun!

###code:
lid = [87 , 5, 3 ]; // [ outer diameter, height, wall thickness ]
pipe = [57.8, 46, 1.2]; // [ outer diameter, height, wall thickness ]
type = 1 ? "circle" : "square";

shower_drain(lid, pipe, rounding=3, holes=undef, type = type);
