- quick rundown:
- Model the "thing". This is super simple -- a "box bag" would just be a rectangular prism, no fillets or anything.

Making a leather box-style bag (easy mode)
Pictured: hard mode. Do not try this at home Bear with me, I'm figuring this out as I go. The goal: make a rectangular prism tool bag, with zipper and handles. It should look pretty good and last forever. And not require a protractor or master's degree. Ideally, just a big rectangle of leather, one good needle + thread, and some scissors. And maybe a ruler (but not required).
- Cut or obtain a rectangle of material. It will be about L+H on one side, and 2H+2W on the other.
- Install the zipper, you now have a tube. Flip it inside out.
- Sew the ends (Width in the middle of the ends of the "tube". (maybe attach a tab)
- Cut out the 'corners', a two-layer square equal to Height/2
- (maybe attach a handle) sew the remaining corners
- Flip it rightside-out.
- try to prevent your wife from stealing it.

concept: 3d print a dumpster, put LEDs in there to simulate fire. Bonus points: internet & use current events to drive intensity.
Dumpster:
- https://www.thingiverse.com/thing:950602
- print all parts at 140% scale
- compensate -0.02mm "bin"
- use green PLA (Matter Fiber HTPLA is great) for bin, hinge, sleeves
- use black TPU for wheels & lids
- use piano wire for "bar" (hinge pin); bend one side
Tea lights:
- https://www.amazon.com/gp/product/B07YJGQQ8K
- wad up a tissue in the bottom to hold the flame higher
Bonus:
- Particle Photon (fave IOT platform)
- APA102 or WS2811, high density, 10 LEDs
- 128x64 OLED display for stats
The intensity feed:
- IFTTT: if "user posts on twitter" then "publish an event to Particle". It's a public event, the data is entirely the contents of the tweet. The device subscribes to / receives that event and uses the number of characters to drive the intensity. Over time the fire dies down to a relatively low smolder.
- In the video below, the unit starts at minimum intensity and reacts as if to a 45-character tweet. Over the next ~48 minutes the intensity will die back to the lowest value (unless there's more tweeting).

(notes to future self)
HTPLA from Proto-Pasta is reallllyyyy good in the kiln. Other PLA (lookin at you, Jessie) kinda sucks.
200F / 2h: no warping, good result
210F / 2h: warped, layer separation
205F / 2h: warped (but not as bad as 210)
200F / 2h: wood PLA + HTPLA, minor warping in wood (barely noticeable), no separation
