That’s fun… The original is theoretically “optimized for resin printers” whatever that entails… Anyway…
Out of those 3 it looks like one lis “share” so there’s no remix. I wondered how it works and it looks like Bambu has something like “claim your account” there where user can just connect their account and reap the rewards. Cool.
2 Others - one has “added base” so if you stretch the remix definition to allow such mod as a remix then it’s “fine I guess”.
That leaves that one that claims to have “tweaked the structure” which I kinda doubt… If anybody wants to play “is it remix or is it not” and wants to try CloudCompute here’s how to do it (assuming you find and install CloudCompute):
- Open up the STLs in CloudCompute
- If you’re lucky, they are the same scale, size and position. If not - follow the cloudcompare wiki on how to align meshes. I had great success with automatic registration with ICP but it seems to work best when models are actually nearly identical. This can also calculate the scale which can be useful to show that all that was done to model was resizing
- in the treeview select vertex objects from both STLs go to Tools->Distance-> Cloud/Mesh distance and let it compare the distances.
- After computation it’ll show the mean and std dev of distances and the visual distance will be colored on scale from blue to red where blue means “it’s in the same spot” and red is “it’s waaaaay over there”. If the whole is blue then you know for certain it’s the same. If it’s red then it might look the same, but it’s different.
Whole operation takes couple of click and around 2 min calculation time on my 10y old laptop for models with over 1M vertices.
I only recommend doing that when one is actually ticked off by the “remix” or clear copyright violation to spend about 10 mins learning cloudcompare, 2 mins of calculation and about 1 min of sending report to MakerWorld with screenshots showing clearly the issue and clear wording so they have no chance but to accept the report.
