Hey all - After having zero luck finding the correct dimensions for an Elegoo Saturn 2 FEP spacer, I made my own. It's not a complex model to replicate, however I have found that this one works perfectly for me. And believe me, I've tried a lot...

If you print in FDM, please sand the top and edges a little to prevent damage to your FEP sheet during installation - For resin prints, please make sure you clean well and cure properly - I found printing this in resin, then curing, added 0.5mm to the surface, effectively changing the tension of the tune. I'd use FDM, sanding doesn't affect the tension in a bad way!
