It's similar to other ones in the community, not Alexander's design.

I just looked at his website and yeah that seem to be the case. Though his design is superior. Note that I designed it with a video of his in mind from a while back. But yeah I'll contact him to see if he is ok for this to be here. This was just meant to be shared to friends but I guess it's not the right platform.

Bruh isn't this just a copy of Alexander Chaple's design. It actually looks as though you've downloaded the stls and uploaded them.
