I love me some 3D printing, but if you need a fast gasket I would buy a roll of gasket material and cut it to size. Most auto parts stores stock a variety of materials for this use.
Gasket mating surfaces can be... extremely fickle, especially when one of the two sides is stamped sheet metal or even plastic. Too little torque on the fasteners means there won't be enough clamping force, which means leaking. Too much torque on the fasteners will dimple the stamped or plastic part, which means leaking.
If you're using this in a low temperature application with beefy mating surfaces, TPU could work fine I guess. It still seems like more effort to get a dimensionall accurate enough design than to grab a roll of gasket material and an exact blade.
I do this on my Xtool M1 with both the blade and laser cutter, both seem to work fantastic though the laser cutter leaves a little burnt residue.
Super easy to come up with the trace, just throw your part on a flatbed scanner, scan and trace it out in FreeCAD and send the SVG out for it to cut.
BBK actually doesn't make a 61mm gasket (I believe for 3502 part number), it still has 58mm holes so you're really better off just going custom when it's $20 for the wrong gasket lol that you have to hack up anyways.
I love the reduced time to get things with this approach. I just keep enough of different types of FelPro gasket paper on hand and have them cut as needed, way faster than Amazon!
My friend has been running a Nylon IAC spacer ln his turbo 351W foxbody with two laser cut gaskets to go with it for over a year with hard racing in high temps and all of it has held up great.
Most of the gaskets I've made are for oily things and I'm not sure all would be clean enough and/or fit on my flatbed. That does sound like a very fast/effective method though! Especially if you found yourself needing to do this fairly frequently.
Photographing fairly flat angle with your phone and then scaling the imported image using a dimension such as the diameter of a screw hole or something will get you VERY close as well for more prohibitive items!
3D Scanner is really worth while if you do a lot but that's a bit of a barrier to entry for most people currently but hopefully follows the trend of printers getting better and more affordable.
