There are two models here. The first is my prototype which is usable straight off the print bed. The second (V2) has a taller heal to allow non slip rubber feet to be stuck to the underside to better grip the work piece.

On a Prusa Mk3 or a printer with a similar sized bed, you will need to turn the model so it sits diagonally on the bed to fit it on.

Print instructions

Use thick sides and 20% or more infill to ensure that the push stick is strong.
