Tumbleweed mitre box for cheap bastards

thingiverse

For some reason, I enjoy conserving cooking fuel. Mostly when i cook outdoors i use a "Cobb Grill" which is a clever, gadgety Australian grill that, depending on how you configure it, is more like a charcoal-fired oven, or just a cooktop. With some accessories, it is really versatile but expensive. It has a small charcoal basket that sits in a stainless steel bowl that reflects heat pretty well, so you can use minimal fuel to get your food cooked with a little smoke flavor if you add a little bit of wood. The default cooking surface is a slightly domed diffuser sort of affair, similar to a Korean bbq. Anyway, I digress. The point is, using a whole firestarter to kick off 8 briquettes is pretty wasteful. newspaper soaked with old cooking oil sorta works but not as well as the "tumbleweed" style bundle of inner pine bark saturated with (pretty sure) beeswax. I also have the Weber "Smokey Joe" kettle grill that I use when I need the more extreme heat and/or need to feed more people. With some experiments, I have found that I can kick off a full load of coal for the Smokey Joe with half a tumbleweed, and even the 12-15 briquettes for the larger 'direct grilling' cobb basket with a third of a tumbleweed. So I threw these miter boxes together in tinkercad. Because why not. I've only tested the combo half and third printed in PETG. I'm printing the thirds box in a stiffer TPU right now. I wouldn't recommend PLA because it helps to be able to squeeze the box while you cut. I recommend a thin cheap serrated blade, something from the dollar store in stainless steel. The 30 and 45 degree half boxes are offered just for giggles.
