Lithophane Arc Frame

So i made a few lithophanes as christmas gifts for my family, really loved the arc design but i couldnt find any frames for them so i made my own, this frame holds lithophanes in arc form of 20x15cm feel free to resize and maybe make it bigger , i will update this frame at a later date because i have a few more tweaks i might want to add but id say as is it works pretty well .   Also feel free to post your makes here and comment ideas to improve the design.
