I built this remix up from scratch. I have included both the STL and step files, in case you would like to modify it yourself. 

The original was a bit loose up top and so it didn't fully latch securely. I also wanted to shift the arm to the left some more, so that I could maximize the height of the print that would still fit OVER the vat while dripping. I think I maintained the same angle, if not a bit more, to make sure the resin can overcome the lip easily. 

I also added chamfers to make it look a bit more finished. 

I recommend you print this with extra walls and infill to make sure it is strong and won't drop a build-plate into your vat. I am sure normal settings will be fine, but why take the chance?

(The photos show a curved edge-I have updated the file to remove this for a bit of added stability.)
