Reporting back: Some of you may remember that earlier in the thread this IP-67 container carried at Home Depot generated a lot of interest:
because as a drybox it was (and is) a good size to store 4 rolls of filament.
Well, good news! Walmart now carries two series of IP68 (note the upgrade over the former IP67 rating) containers. One is by Sterilite, and the other one is named Bunker, made by ez-storage, the same manufacturer as the IP67series at Home Depot).
Worthy of note is that the Sterilite series is a lot less expensive. That said, the wall thickness appears to be different in the different linups. I measured the wall thickness of the lids, since that affords the easiest access for calipers. The Sterilite measured about 1.8mm, the ez-storage from Home Depot measured about 2mm, and the Bunker measured about 2.3mm. The Sterilite and the Home Depot ez-storage seem to be made from roughly the same type of plastic (maybe PP?) whereas the Bunker series seems to be different (according to the description, the lid is polycarbonate). There were no recycle numbers that I can could see, so I can’t be sure, but, in addition to wall thickness, it might have an effect on the moisture transmission rate into the different containers.
Lowes now carries IP68 containers in its Kobalt line. On its face it looks very similar to the Bunker Tough, but more expensive:
This thread has been dormant for a while. Anyone discovered any other good finds?
