You can make a Vat out of PETG too, easyer to source and work than PC and kind of the same characteristics 
I’ll post back the source files for the Form One vat once i get my hands on one.
In the mean time here’s a link for some Cad files shared by another Master, unfortunately he no longer has the STEP files 
and the other is designed on Sketchup
Will be a good starting point to a Open rebuild tho 
Just found out one can use peopoly moai vats with a small mod to the back of the vat. Will eventually try out the FEP vat from my moai too
I have put up a photo album with my findings on the form1+ hope it helps someone
I guess Moai took the Form1 VAT as reference hehehe
No luck with Form2 VAT CAD’ing? 
Funny! Form2 has a chip, you know, for good or bad has been argued already. Unless you meant using the Open settings? The CAD for the Form2 is straight forward, a basic structure really.
The chip is not an issue. I got a 3D model of the tank as well.
The question is, what is the advantage? Making your own tanks? It saves you a lot of trouble to just buy a tank, use it up, replace the acrylic sheet with glass and recoat again.
You have a model of the tank? have you shared it?
Another option is to buy there LT tank. There suppose to last ten times longer. Which might make it more cost effective than re-coating an existing tank.
Looks like LT tanks have as many or more issues than standard ones lately… You don’t surf the Facebook group right?
Nope, I don’t surf the Facebook group. And I am using a LT resin tank. I can’t say I’m having any issues with it. As far as I can tell it’s working fine.
