If you happen to have a 5G S10 (which happens to be my favorite phone) here’s a case! This includes two versions, one with a leather pocket and one without. The contents of the pocket can be ejected using a 20mm nylon strap (or a little thumb window might be easily added to the leather piece.)

Note that this only fits the 5G version - it’s a different size. This prints without supports, & pictured is a .3mm layer height, although I recommend .2mm or .1mm for a more polished look.
