The file 'Fast & Strong Parametric Basket Weave Desiccant Containers (with Hygrometer) (SCAD) 3D Printer Model' is (zip,stl) file type, size is 22.4MB.
Recreated based on PsychProd's basketweave/quasi-vasemode concept here, as well as its remixes (e.g. #5204468, #5168851, #4976590) and the cited prior works (e.g. #4508179).
The idea is great, but perhaps it was limited by the method of generating the cyclic geometry needed for the container walls. There were complaints of weak walls for obvious reasons, so i printed a small one. I tried to flex it, and it split. That made me doubt the strength of the larger containers I had intended to print. I also wanted to modify the models for my needs, but the STL files are so full of errors that I can't import any of them into openscad, and it's beyond my meshlab skills to repair the models.
Also included is an SCAD file for rectangular boxes of the same fashion, based around a similarly inexpensive hygrometer model. I had not seen any implementations of the concept in prismatic containers at the time, so I figured it would be best to add one.
Only after I completed both files did I find this hexagonal model. While MysticalDork has tried to resolve the same limitations in PsychProd's design, it's still just a set of STL files.
I don't know of any prior published basketweave container models which are parametric, but now we have some. I've covered round canisters and rectangular boxes. If you want something else, these files contain modules to generate the weave pattern as either flat panels or cylindrical tubes. You can copy that and build what you want.
The SCAD files have lots of printing and design notes. Included is a library of premade STL files for 25, 40, 50, and 70mm dia canisters, as well as a handful of rectangular box designs with assorted lids and accessories.
BENEFITS:
CAVEATS:
TL;DR: They're customizable and a good balance of speed, printability, stiffness, strength, and minimal material usage. They're good and cool and will make you look smart. All your friends will be impressed, and you'll finally be able to sleep restfully after all these years.
EDIT: As a matter of course, now that I've posted these files, the other implementations of basketweave desiccant containers finally come out of the woodwork. It's almost like the behavior of search engines is less dependent on the query string than it is on collected user data. Imagine that.
Regardless of prior attempts to improve on PsychProd's concept, this is the only known implementation in SCAD, and it's the only one to provide both canisters and boxes. It's also going to produce the strongest containers for the material used, since none of the other square-weave models use any sort of web overlap (referred to in the files as ilh (interlayer support height)).
Regarding the influence of ilh on strength, I did 3-point bending tests on 20mm wide panels (40mm support distance). When compared to ilh=0, ilh=0.4 increased the load required to break 3mm thick samples by 50%. The strength of thinner 2mm samples was more than quadrupled. In other words, webbing overlap/intersection makes panels significantly stronger.
