Door Catch Grommets for Old Delta 28-185 Model Bandsaw

This is a quick and easy TPU print to replace the rubber grommet door catches on old Delta model 28-185 bandsaws.

Much as I like to spin a lengthy yarn, there's little here to tell: I was gifted the machine, but the original latch rubbers had failed and no longer held the blade compartment door closed.

I copied what little was left of one original grommet. It seemed to have the remnants of a flange at its base - although it may have just been flashing from when it was moulded all those years ago. It seemed to make sense to me to have a little noise damping between the door and the catch, so I incorporated it into the design whether it was meant to be there or not.

A little bit of trial and error followed while I adjusted the dimensions to ensure the catch held properly, yet released when required. I also experimented with minor size and infill variations. But it turned out that a bog-standard 2 perimeter wall, with a 20% infill, provided perfect compression properties for my machine.

Not much of a design, I guess, but I hope someone can use it! I also think it's about time I looked at replacing those retaining nuts. Looks like they've had a hard life like me.

So it's all yours, perfectly free, and there's no catch!!
