Kyiv Designer Sells 3D-Printed Shoes as STL Files

From Kyiv Fashion Week to 3D Printing

Sofia Rousinovich built her ROUSSIN streetwear label on the runways of Ukrainian Fashion Week in 2019. The brand was gaining momentum until the full-scale invasion forced her to rethink everything. Based in Kyiv, she redirected her design skills into digital and additive manufacturing, eventually teaching herself 3D modeling and printing from scratch.

The result is a new footwear collection that she sells as digital files. Buyers download the STLs and print the shoes themselves on a standard desktop FDM machine.

The Collection

The lineup includes skeleton-inspired sandals, lace-up swan sandals, and Voronoi-patterned heels. There is also an everyday sandal printed in a single piece with an integrated button closure. That design prints flat, needs no supports, and requires zero assembly afterward.

Rousinovich used a Bambu Lab printer and Kexcelled flexible TPU filament to produce the pictured samples. The fishbone-style sole combines variable texture and density for support while the upper stays porous and lightweight.

Selling Files, Not Shoes

Rather than operate a print farm or hold stock, Rousinovich publishes the models on Patreon and Etsy. The approach cuts shipping, waste, and overhead. She also offers 3D-printable accessories: spine-themed sunglasses, a skeleton handbag, and butterfly embellishments for swimwear.

Her Instagram shows experiments like printing directly onto fabric, pushing the material beyond static objects. At a time when Ukrainian designers face disrupted supply chains, turning a home printer into a production line is more than a gimmick. It is a practical way to keep creating.
