Subject: use 2 measurements to calculate shape
X-Git-Url: http://challenge-bot.com/repos/?p=ozzloy%40gmail.com%2F3d-printables;a=commitdiff_plain;h=1b6eae45203775e89afe4f7ac4fdc7ac9073aa05

use 2 measurements to calculate shape

final shape depends only on how much higher shelf needs to be
and how wide foot of shelf leg is
