I replaced the cheap plastic resin tank on my Alkaid printer with an aluminum one designed for an Anycubic Proton Mono printer. Example here - https://www.amazon.com/dp/B08CJZ711T?ref=ppx_yo2ov_dt_b_fed_asin_title
The original had a different clamping arrangement but the vats are the same size. These clamps fit the new tanks and provide enough clearance for the lid. The offset bottom sits on the base and tilts slightly to apply more clamping force.
You will need two longer 4mm screws.
I printed in PTEG with 100% infill.
