Looking for soft flex filament
I'm trying to print a plug that goes in the back of a replaceable ink cartridge for an Epson 3880 printer. I have some Matterhackers FLEX filament which I've used for other things, so I printed one using that. Unfortunately, the material is a little too stiff to seal well, at least for a cartridge with PiezoFlush in it. Does anyone have suggestions for a soft, silicone-like filament?
Not one printable on a Mk3 ... but you have another option.
Use the part file you have as a negative to make a mould:
Design a block, perhaps in two parts, and subtract (difference) your part from the block to make a void into which you can pour two-part or low temperature setting silicone of the desired softness. You may need to tweak tolerances to account for thermal contraction as the part cools and you may need a coat of separator to prevent the part sticking to the mould.
Cheerio,

Thanks, may try that. It's kinda small so not sure how easy it will be to inject the silicone. Need to use a syringe most likely, so I guess I need both a hole for injection and a hole for air to come out.
