There are plenty of Youtubevideos that can help you out Pheonix. I never made one but watched my little bro make them*. They order the cubedioramas on Amazon and stabilize the printed art with a layer of foam. Definitly check it out and do your own version of it! Most are made about Pokemon or Mario but i bet you can do awsome jrpg dioramas too.

Edit: Also i would never recommend buying them online because they are very very pricey and not really that hard to make. You dont need to be that artisticly gifted to do such dioramas it should work fine. My little brother could do them with a bit of help from my sister so you should too. There are even free layouts shared that you can get for free. Its a very cool hobby and if i had more time i might get into it too.

And OP should check on Autism go see a doctor

Also excuse my english

The second thing why i recommend doing it yourself is because i dont want you to support ***holes like OP. Pure Cringelords

There you go: https://youtu.be/7Q5Jkt2BNmU The assets are given or looked up online and the dioramas are here: https://www.amazon.com/dp/B097YTQ5ZB/ref=mp_s_a_1_14?crid=2ZCS6LYYQCRYB&keywords=Diorama+Box&qid=1648883790&sprefix=diorama+box+%2Caps%2C189&sr=8-14

That are the first one that came out. Im 100% sure there are also ones of right size if that one isnt.

This + Buying a new cutter and glue would make a 1x Investment of 20$ and you get 4 Dioramas rather than ordering one for 50-80$ on etsy. You safe yourself 1 or 2 hours but pay so much money. Not worth at all buying online
