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.

  • While the Nazis did push programs like the VW Beetle

    Another point of order about that in particular, zero regular citizens who paid into the Beetle scheme with their little KdF-Wagen Sparkarte stamps actually received one. All of the Beetles produced went to Nazi party leaders, and then Germany went to war. Hitler may have successfully sold people on the dream of an affordable personal car but he literally used it as a mechanism to embezzle money from his own citizens which he stole and used for war production.

    5 Mark die Woche musst du sparen wills Du im eignen wagen fahren, my webbed foot.



  • Superglue works extremely well on coffee mugs. I have one that’s got the handle held back on with superglue and it’s been that way for probably close to a decade at this point. The stupid 1970s ceramic tile toothbrush holder in my downstairs bathroom is also held together with superglue…

    I’m not entirely certain I’d be keen to try putting back together any of the liquid holding parts of a mug with it, but if you did it carefully and very thoroughly it wouldn’t surprise me if that worked as well.


  • Unless you’ve deliberately reversed your walls/infill printing order, the default is to print walls first. Your print head and nozzle won’t have any reason to leave the perimeter of the model even if you’re printing multiple examples of the part until the entire layer is complete on one of them. It will move to the next part in the array only after finishing the infill, which is well after your problem may have occurred on either the inner or outer perimeters on any particular layer.

    I’m not sure what you’re on about with top fill. I didn’t say anything about your fill pattern or percentage.


  • Your nozzle won’t travel anywhere outside of your model’s outer perimeter because it has no reason to (unless your g-code is super borked, see my comment about your slicer above) but it will be dancing around within the space between the outer perimeter and center of your model many hundreds of times. Any extrusions pulled off on the outer perimeter would stay somewhere within the model.


  • Those sections of extrusion are being pulled away from the print as the nozzle moves, because for whatever reason they are not adhering to the rest of the print properly.

    Increase print temperature, reduce print speed, or reduce travel move speeds.

    Also a sanity check, look at your slicer’s output preview and ensure nothing about that model is causing it to freak out and attempt to print in midair…







  • Correct answer. Even in countries where by and large police aren’t armed, they still have a section of specific very heavily trained police who are armed who can be called in if shit goes down. For sitting on an overpass radaring cars, or showing up 16 hours late to write an incident report for the burglary they failed to stop, or harassing some homeowner about the length of his lawn or the volume knob position on his stereo, or any of innumerable other things the police spend most of their day doing they don’t need to be toting around guns. The majority of Americans don’t, and somehow most of us manage not to get shot on a daily basis despite theoretically rubbing elbows with most of the same criminals that the cops do.
