I just added some variants of this beautiful photo frame by wuguigui. Thanks to wuguigui for sharing this model. You can find detailed information in the original model description.
had to use t8ny dab of glue for the peg, I'll upload my profile where I increased the oeg parts scale 110% so it snaps in snug no glue needed. works great with 4x6
oh and i used a small cut up piece of support (cut into 4ths) for a stand! hot tip of a lighter "solder" or glue it on. that way you can reuse the large support piece that comes off this piece and you can also use a few slices to glue/solder on a lip to prevent photo from sliding
