BluntTongs

Okay you might freak over this, but I've actually been working on a mod these past few weeks, Museum Cases, EXACTLY BECAUSE of the reasons you described, and with similar solutions!! The base display case is kind of not great IMO because of the enforced +45 degree spin plus a random extra amount of spin making it look like my seraph is just haphazardly throwing these things into a glass box instead of actively curating the thing, on top of it being completely worthless for displaying butterflies. If there's gonna be what, like 169 different butterfly variants? We might as well have something *nice* to show them off in. Posting in spoilers so I don't blow out the page here with all the screenshots of a mod. Sorry for making this a "check out my mod" post, I just got excited because this thread was linked to me and I really wanted to share my work since we're sort of on the same track! ...No release window yet because I'm pretty busy during the week, but we're getting pretty close to having something worth installing
