Thank you, this app is awesome !
I just stumbled upon a small bug with the fin supports on the rhombic d12 and the d8, they don't seem to be manifold and chitubox doesn't seem to read the models well (i've made a gif to show the issue)
I haven't yet tried to print it as is, maybe it will still work, anyway it's not such a big deal !
Other than that, your app is perfect and has saved me so much time creating my masters, thank you again !
