I modeled this, but I consider it a remix similar to the Helmi74 lid with some subtle difference and different dimensions. I tried the Helmi74 lid and it would not fit my vats. It was a couple mm off. I measured the stl and my print was pretty spot on. I measured my vats and they were much different for some reason (couple mm).
I did notice there are some pretty decent variances in the width of the acrylic Peopoly uses, but I tried to make this to fit the thickest pieces. It fits my vat very well.
