Parametric Rubber Foot Mount
by k1nc41d, published
A parametric upgrade to the printrbot foot. The original had a flat bottom to make the printing easier. This version has a lip to keep the rubber pad from sliding off. Also this mount can be customized to almost any application.
Attached images show how the original foot pad fails. :( The lip has solved this problem for me. :)
BoardThickness = 6; // The thickness of the board you will clip the foot to.
RubberFootRadius = 6.5; // The radius of the rubber pad.
Recess = 2; // The height of the lip holding the pad in place.
RimThickness = 1; // The thickness of the lip holding the pad in place
ClipHeight = 6; // How tall the gap that grabs the board is.
BaseThickness = 3; // This is the thickness of the material between the rubber pad and the board.
I found that flipping this part upside down yields the best prints. The posted STL was created with the above parameters, and is what I'm using on my PrintrBot LC now.
