Personally, I would abandon it all together though.

https://www.amazon.com/Sovol-Anodized-Aluminium-Preinstalled-Silicone/dp/B08G82HSTD/ref=sr_1_4?crid=1Z9RIF6ZTQO11&keywords=Sovol%2B3D%2BPrinter%2BResin%2BVat%2BAluminium%2Banycubic%2Bmono&qid=1643161862&sprefix=sovol%2B3d%2Bprinter%2Bresin%2Bvat%2Baluminium%2Banycubic%2Bmono%2Caps%2C68&sr=8-4&th=1

You can buy 2 of these for the same price (they include a pre-installed FEP), and can then replace them with literally any fep like normal moving forward instead of the silly frame thing. This also lets you use nfep next time!

If you order the two or just 1, either way it's the way to go. They come with FEP already (so basically 2 FEP sheets included) and are 10x cheaper to replace the FEP moving forward (instead of the plastic vat/fep sheets you need to replace for the stock vat)

there is no way two trays with FEP is cheaper than just FEP....

Here's the Amazon link for the Anycubic FEP replacements: https://www.amazon.com/dp/B08PPDJJM1

$45.99 for two new FEP screens, nothing else.

The Sovol two pack which is two vats with replaceable FEP is here:

https://www.amazon.com/dp/B08G82HSTD

$43.99 for two new aluminum vats with FEP and covers.

I'm going to go the Sovol route so I can replace just the FEP in the future. Their five-pack of FEP replacement sheets is $18.99 here: https://www.amazon.com/gp/product/B091TDV8XL
