Summary

Like the ergonomic handle, but wanted something that used that handle part on a replaceable (cheap) piece of 2x4. This handle was modified to be screwed on to either to 2" surface or the 4" surface and give some additional meat for a saw to play with in even of an argument over what should occupy the space. Actual pushing should be done by a rectangular piece of 1/4" plywood screwed on to the back edge of the 2x, sticking down between 1/4 to a 1/2 inch, depending on the thickness of the wood you are planning to use for.. Two screws into the end grain, predrilled, and long enough that they won't pull out. Advantage of this design is that the bulk of the block is provided by cheap wood and not a lot of print time. More time building. Would work on a 2x2 also with less weight but with less distance from the blade. Even narrowed down to a 1" wide, but that leaves less mass for the 1/4" end plate to attach to. .
