Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • Anyone who is planning shenanigans and doesn’t take phasing or teleportation is asking for it. Sooner or later some government entity or another is going to try to put you in some kind of prison and you’d better have an escape card. Especially if you also take immortality. If you’re immortal and some asshole Cask of Amontillados you, you’re going to be pissed off about it forever.

    And is “divine powers” just a free combo deal of magic, invisibility, and immortality?










  • Not really. You can print it out of ABS easily enough if that’s a concern, given that there is a good chance that is what the knob on any given residential range or oven is likely to have been made out of by the factory anyway.

    As a matter of fact, since this is directly in my wheelhouse (not that wheelhouse, the other one) vis-a-vis both 3D printing and whitegoods, let’s take a look.

    Being in the unique position to be able to do so, I grabbed a knob off of a random smattering of ranges. Here’s what I found from the ones that didn’t require taking them apart further to find the markings or scraping at them with a knife or something (hey, there’s the other wheelhouse):

    • Maytag (Whirlpool): Stamped “ABS” on the inside.
    • Bosch “Industrial Style” (similar to OP’s): PBT
    • Whirlpool: PET
    • Verona: ABS
    • GE Base Line: ABS

    PBT has a pretty similar melting point to ABS at ~235° C. With ABS it’s complicated, but I print ABS at 260° C for what it’s worth. PET is also typically given around 260-270. So these are all pretty similar to each other.

    TL;DR: You should be fine with ABS.
