!!Please read it before you broke your glass!!
Hey, i liked the magnetic pate on my older Photon Mono SE, so i installed one to my Photon ultra too. (Its the same size too)

Its made for the Sovol magnetic buildplate. Its adds about 3.5mm extra to the Ultra buildplate.

Always check your magnetic buildplate thickness, if its larger than 3.5mm its might break your glass!

My magnetic sheet with the plate is about 3mm, so i added an extra 0.5mm to be sure.

You will need a bit longer screws to set it up.

I printed on my Prusa (FMD) but it can bi printed with anything.
