This is an insert for a bandsaw (the replaceable part that the blade passes through in the middle of the bandsaw's table), with holes to allow for dust to fall down and also be pulled down by airflow from a shop vacuum or dust collector.
I am modeling my own version of this with my specific dimensions, but I thought I'd ask if it would be easier for the 3d printer to do round holes instead of the hexagonal ones.
(For reference, the printer that I have access to is a Prusa i3 MK3S+, with a 0.4 mm nozzle).
Edit: The fluidity of movement being better for circles is what I was expecting. When doing a circle, each small segment of straight line is only slightly different than the previous one, whereas the hexagonal hole would require abrupt changes. In my case, the final appearance is not critical since it's just to let dust fall through. The version with circular holes might be a bit stronger as it removes a bit less material. I used OpenSCAD to create the model, since my geometry is pretty straightforward. I was starting to mess around with FreeCAD (out of curiosity) but then I remembered that in OpenSCAD I used the trick of 'facet numbers = 6' to get the hexagons, so I just changed those to 60 (thank goodness for being able to define and use variables) to have the same placement of holes.
The printer isn't mine, it's in a public library and I don't want to abuse it so I will only print the one with circular holes.
