Printed red one in PLA on an Ender 3 S1, 7+ hrs, the grey is PETG (which prints at less than half the speed of PLA) and it was about 4 hrs on a K1 Max, that's not counting the half dozen restarts i needed until I had dialed in a working set of parameters for good adhesion, ended up using glue on the deck. I do not recommend PETG for this jig. Both worked fine, using it to create the wooden bents for my garden railway trestle bridge. The 4" one is now done, a 2.5" one without a middle cross section will finish the trilogy of jigs for this bridge build. Might post a picture of the finished bridge ... it is a summer project.
