Flambeau bin ("Tuff Tainer") replacement latch for most small/medium bins: 3009, 4007, 5007, 7004, etc

On a per-hour basis i probably should have just bought these (are they even for sale?) rather than designing it … but here we are :)

Functions as the original.  I print mostly 0.6mm, and didn't feel like swapping nozzles, so the examples you see are 0.6mm.  If you use 0.4, they will have sharper features, obviously; 0.6 is a stretch for both ends for retention features … but it's working fine.  Note I radiused my part so as to provide more flex/spring - the OEM seems like ~Polypropylene, which is very soft.  I used ASA, so wanted to ensure it has some give if needed.  PLA will be similar (ie much stiffer than PP, so you should also be well-served by a feature like this).  YMMV, but it certainly shouldn't negatively impact functionality.

The model INCLUDES a small brim, and a vertical support - I print mostly ABS/ASA and for a narrow, tall-aspect part this sort of thing is ~required, but if you use the slicer's brim it would require cleanup of the interior angles.  The built-in “supports” as such snap off cleanly, requiring no cleanup.

Step file included.  Hope this help!

PS: Finding the box sizes is annoying.  Here are a couple I have, and i think are some of the most common sizes:

• 4007: 11" L x 7.25" W x 1.75" D with 6 fixed compartments front/back (along short dimension. ~ $6.50 msrp
• 5007: 14.25" L x 9.125" W x 2" D with 4 fixed compartments side/side (along long dimension). ~$8.50 msrp
• 7004: 16.5" L x 9.75" W x 3.25" D with 4 fixed compartments side/side, front most is fixed-divided into 4 fixed subsections, rest are with dividers. ~$16 msrp. FWIW, as of 2025 i haven't purchased any of these with the newer replacement latch style - even this year they are still coming with the live-hinge (eg molded in, non-replaceable) latches.
