This is simple footwear for makerbeam well euh beams
It is in openscad so u can change the parameters.
There are simple version en versions that are a bit overdesign but both work fine.
O there also a experimental corner piece it is a bit hard to print because of the overhangs
for more info on makerbeam see http://www.makerbeam.eu/ and no i am not working for them ;-)
Wel just print and put it on on your makerbeams
If it does not fit open Foot.scad and change the value
makeSpace = 0.15 into something lager :-)
If you need more then 4 feet then change
nrOfFeetX = 2;
nrOfFeetY = 2;
