Advertisement I have some acrylic terrestrial enclosures (purchased from a reputable dealer) and either the lids or the enclosures themselves (or both) seem to be warping. The top is no longer flush and the lid dips down a bit (slight gap on the L enclosures, more pronounced on the XL enclosure). The hasps used to snap open/close with ease but it's now becoming more and more difficult to the point of jarring the entire enclosure every time I need to open it. Is there any way to prevent further warping or somehow reverse it? Substrate is dry with only a water dish, no misting, no heat lamp or heat source nearby. My apartment is usually 60s-70s deg F during winter with occasional use of the central heating on colder nights. I believe the acrylic is 3/16" on the sides and 1/8" wrap. I like the look and uniformity of the acrylic enclosures and hope to keep using them rather than using glass and having to make custom lids. I also don't have a lot time to make custom enclosures which is why I decided to spend the extra cash and go the pre-made route. Basically just wanted to see if I could somehow fix the warping issue. Thanks everyone.
