Fluting Pliers Gridfinity Holder

First of all, there are a bunch of different variations on fluting pliers out there.  I bought mine over 25 years ago, and I don't remember who made them or where I bought them.  There are no markings on the pliers themselves.  They resemble the ones currently sold by Aircraft Spruce (which is a US Air Tool Company product), so if you are looking for a set to fit this bin, that may be your best bet.  Mine are all steel; from what I gather from a web search of what's out there now, some of what are available may be pot metal castings with steel inserts at the wear points.

Anyway, for those who are not aircraft builders or sheet metal workers, a fluting pliers is meant to press small flutes into a sheet metal edge, to either add or remove curve from a sheet metal part.  I used mine to remove curve from aircraft wing ribs after they were removed from the forming blocks that I used to bend the flanges.  Sorry, I don't have any fluted parts easily available to photograph as an example.  If this Gridfinity holder is of use to you, most likely you didn't need any of that explanation.

Like my other Gridfinity models, the base is altered to accept 6x3 magnets as a press fit, with the upper surface of the magnet holes modified to make the slicer bridge across correctly for a clean result.  Due to the size of this model, I have included sacrificial “mouse ears” in the CAD to give the ends more surface area to help prevent them warping off the bed.  These will need to be removed after printing.

To fit this model on the print bed of a Prusa Mk3/Mk4/Core1, you'll need to rotate it 45 degrees.  When you do that, be sure to remember to change the fill angle to zero degrees instead of the default 45 degrees.

The unit pictured was printed out of Overture PLA on my Bear upgraded Mk3S+, using a 0.6mm nozzle, at 0.3mm layer height.
