I've been tinkering with this design again! Instead of having a loose silica tub or sachets in our sugar jar I wanted a fixture in the lid. So I started with the 40w x 20h tub, chopped them to end up with a 40x7 tub, and used my cutting mesh on the lid, then attached the base with double-sided sticky tape, filled it with silica and screwed the lid on. helps stop the sugar clumping the the jar :o) Silica tubs with separate lids would be too bulky, this design lends itself to this application perfectly so I'm making more for our other jars now. Red Elegoo PLA+ just happened to be the same colour as this jar's lid.

Wow, they're MUCH stronger than I was expecting them to be, and a perfect fit too!
I made the 30-20 just for starters, but will be printing more and some other sizes.
Exactly as instructed, 3 bottoms, 0.6mm walls with 0.4mm nozzle. I found the layer instructions slightly confusing and went with 0.2mm layers and printed top and bottom separately. Also confused about the walls - there's only one wall cos it's vase mode but there's mention of "double walls" in the instructions.
I use PLA+ for almost everything, so used that, and it's got a slight flex but no feeling that it's about to snap. Perfect for storing little things. Thanks! :o)
Astonishing how cleanly it prints, even if it had been at 0.4mm walls, but extruding 50% more than normal it's still pristine and spot-on. In fact, hold on a moment.... <scuttles off to the sink> ... YES, it's actually water-tight, hahahahah, amazing!

@Gigabeast I'm glad you like it :) Double walls refers to the closed container, a wall from inner part and lid each.
If you print the lid with a different layer height, say 0.17mm, screwing the lid on or off is smoother.

@DrJones AHA, I understand now! Thank you very much :o)

Thanks for this genius containers!
I used top and bottom to cover up the clear parts of our house water filter (so algae won't grow inside)
Very well done!

Great design!

Very nice design, woks so well. I printed the 30_30 model to fit euro coins.

@Blueberry I added a version for 25 2€ coins (in "custom" folder); I use that, too :)

This is amazing. I'd love to use this threading in other models, to make containers that these containers can screw into, and so I've been trying and failing to reverse engineer this (I use Rhino for modeling). What can you tell me about the pitch and profile used in the screw?

@DrJones

@talg_453974 I'm glad you like it! The pitch is 4mm and the tooth height is 1mm. The profile for the inner cylinder consists of 4 sections: valley 1.2mm - 45° incline 1mm - crest 0.8mm - 45° decline 1mm (total 4mm=pitch); the outer cylinder is outset to have a constant distance to the surface: 0.7mm (for it's outside), resulting in approximately 1mm for valley, incline, crest and decline each. The number of starts depends on the diameter and can be easily counted. Have fun!
