Your old $15 Olfa knife and a metal ruler" is pretty much the gold standard, honestly. I had a buddy who tried that same Amazon cutter and it went dull on him after two days, but the kicker was when the blade actually chipped and sent a little metal shard flying (he still finds it in his rug sometimes). He ended up getting one of those cheap desktop rotary cutters from a craft store for like $25, but that thing wobbled so bad the cuts were all crooked. He finally gave up and went back to the Olfa and ruler too, and he's convinced that's the only way to go for small runs (he does zines for fun). So yeah, I think you're on the right track sticking with what works.

Knew a guy who printed a custom topo map for a week long canoe trip through the boundary waters. He laminated the thing with packing tape and it still turned into a soggy, unreadable mess after one afternoon of rain. He ended up having to guess which portages to take and we took a wrong turn that added like 6 extra miles of paddling. Dude was so mad he threw the ruined map into the campfire that night. Digital backup with a solar charger is the way to go for real.

I saw @abbyg14 mention that same thing, old bubble levels are way more reliable.

and I swear I read something similar in an old gardening book my dad had from the 80s. It talked about how plants that get too much water and fertilizer end up with weaker root systems because they don't have to work for anything. They get lazy basically. Same with lawns, if you stop cutting it so short and let the clippings rot back in, the soil gets healthier on its own. I've been trying it with my hostas this year and they're actually looking better than when I was obsessing over them every weekend.

$120 is wild for something you knew was gonna be a gamble. You saw those weird hands online before you bought it, right? Everyone's seen the melted wax faces. Just feels like you set yourself up for disappointment. D&D concept art is specific, you need consistent character looks. These tools change up details every time you hit generate. If you really want to mess with AI for D&D stuff, free options like Bing Image Creator or a basic Stable Diffusion setup get you the same messed up hands without costing you lunch money for a week.
