  • The existence of rainbow filament doesn’t negate what I said.

    Especially considering, that making it yourself would allow you to customize the pattern significantly.

    I prefer the somewhat more random nature of the homemade version. (Length/size of the color bands, which colors/filaments, order and patterning.)

    You’ll find in life there are frequently many paths to the same ends.






  • The only reason practical engineering is more fun than over engineering is that things actually work.

    But, eh, over engineering things is fun too- at least as a thought problem. If OP thinks some leftover Bowden tubing is too expensive, though… it’s only a thought problem…

    If you could get economies of scale working, you might be able to hawk it on Amazon for 20 bucks, though. (Not that I’d ever… that sounds like a desk fire waiting to happen…)



  • So, hypothetically, could you use a ball end mill with a 1.75mm diameter? Then mill the channel across two halves?

    Basically, something like a halved heater block. Put a cartridge heater on one side, thermistor on the other, take it up to a melt temp and shut off. (Maybe add some cooling fins beyond the intended melt zone?)

    Also, have regrets because this is more expensive than the boden tube method.
