Barefoot 3D printed shoes

Flexible TPU footwear with wide toe room and zero-drop feel. Many are breathable like printed socks; some models use a more closed watertight structure.

Toe

A barefoot River shoe with separated toes for more movement, using the same controlled wave-pattern idea as Onda: interleaved semicircular curves shaped around the foot.

Onda

River’s best barefoot pattern for comfort and durability: a smoother inside surface that can be worn without socks, generated from direct Grasshopper toolpaths with interleaved semicircular curves per layer.

buyprint

Tora

A barefoot River shoe on the simple flat-bottom base, using a small-grid print pattern for a light breathable structure and generous toe room.

buyprint

G1

A barefoot River shoe using the same simple flat-bottom base with a heavier grid pattern: thicker lines than Tora for a stronger visual and structural rhythm.

buyprint

Eros

A barefoot River shoe where the print pattern repeats the word “love” in cursive, turning the structure itself into the graphic surface.

print

Una

A minimal watertight River shoe: simple, direct and focused on the essentials. Una keeps the barefoot-style fit cleaner and more closed than the open breathable models.

print

Mare

A relaxed watertight River shoe with organic lines and a soft visual rhythm. Mare keeps a more closed structure while staying flexible in TPU.

print

Riku

A barefoot River shoe in the middle of the grid family: visually and structurally between Tora’s small grid and G1’s thicker grid lines.

print

Loto

A softer-looking shoe file with a rounded, calm shape. Loto is less aggressive visually, made for a printed shoe that feels closer to a casual slip-on.

print

Koru

A barefoot River shoe built around a spiral pattern, like repeated cursive “e” shapes overlapping through the print path. The name Koru echoes the spiral idea behind the structure.

print

G0

A barefoot River shoe with the same grid pattern and base logic as the other flat-bottom models, printed at 45 degrees with the toe pointing down. That orientation makes the structure a little more closed than Tora or G1 and changes how the same slicing pattern appears on the shoe.

print

Mirai

A barefoot River shoe using the same grid family as G0 and G1, but printed at 45 degrees with the toe pointing up and the back resting on the build plate. The pattern comes from the same slicing logic, but the orientation gives Mirai its own surface rhythm.

print

Tale

A characterful shoe with a less standard silhouette. Tale combines flexible TPU, sculptural form and the surprise of wearing a printed object that actually moves with your foot.

print

Aspys

A barefoot River shoe with the same grid family as G0, G1 and Mirai, printed vertically. The two shoes print as a mirrored pair fused at the collar, then are separated with scissors after printing.

Soled 3D printed shoes

A tougher underside adds protection from water, dust and daily ground contact.

Taka

The thin-soled version of Tora: the same small-grid barefoot idea with a fine sole added for more ground protection while keeping the upper light and breathable.

buyprint

Tryton

The thin-soled version of G0: the same 45 degree, toe-down grid logic with a fine sole added underneath.

print

Due

A simple watertight River shoe with a direct, functional shape. Due keeps the printed form cleaner and more protected than the open breathable models.

print

Yume

The thin-soled version of Mirai: the same 45 degree, toe-up grid logic with a fine sole added underneath.

print

E7

The thin-soled version of Aspys. Like Aspys, E7 prints vertically as a mirrored pair fused at the collar, then the two shoes are separated with scissors after printing.

Air purifiers

Printable purifier bodies for PC-fan and filter builds: HEPA for particles, activated carbon for odors, and shells clean enough to keep in sight.

Roy

A quiet, USB-powered air purifier that just does its job. Cleaner room air from a printed object that actually looks like it belongs on the shelf — no humming appliance, no exposed electronics.

Print files

Max

The fastest River purifier to build. Snap the printed shell onto a standard PC fan, drop in the HEPA, plug into USB — your room is already cleaner.

Print files

Yomi

A flat disc you barely notice. Real airflow, quiet operation, and a soft printed silhouette that disappears into a shelf or a coffee table.

Print files

Eno

HEPA and activated carbon in one tall, calm object. The only River purifier that removes both particles and odors — for kitchens, bedrooms and any room that smells of yesterday.

Print files

Ivo

Serious airflow for a real room. River's biggest mover of clean air, in a long horizontal shape that sits naturally on a sideboard or under a TV.

Print files

Ali

A light, vertical purifier concept with a clean profile. Ali lifts the fan-and-filter layout into a slimmer upright object for desks or shelves where the purifier should look intentional from the side as well as the front.

Print files

Evo

A more evolved purifier body with a strong but simple shape. Evo gives airflow, maintenance and appearance the same priority, so the print feels polished without hiding the fan and filter logic.

Print files

Haze

A purifier design with a softer, atmospheric name and a calm visual presence. Haze is for rooms where the printed filter object should quietly do its job while still making the airflow path understandable.

Ice air coolers

Freeze the water-filled pack overnight, then use the fan to move a colder breeze across the desk.

Yuki

A full-size ice-pack air cooler built from printed parts, a quiet USB fan and a frozen water pack. Freeze the pack overnight, place it inside, and Yuki sends a steady cooler stream across the desk with very low power use.

Print files

Yuki Snowflake

The snowflake full-size Yuki: the same low-energy frozen-pack airflow in a more decorative shell, shared as refined G-code for cleaner internal overhangs.

Print files

Yuki Mini

A compact personal cooler for desks and small rooms: printed PLA parts, a quiet USB fan and a frozen water pack or bottle. It gives a close, steady stream of cooler, drier air without a compressor or refrigerant loop.

Water filters

Activated-carbon water filter designs with controlled toolpaths, food-safe materials and practical tap workflows.

Jem

A polypropylene tap water filter for activated carbon. The flower-like top opens for filling, the body attaches to standard taps, and the bottom grid holds carbon while water passes through. Joined G-code keeps the water path cleaner by reducing micro-stringing.

View design

Jusy

A handheld PCTG water filter used beside the tap: remove the protective cap, hold the body under running water with one hand, and fill a glass below with the other. Food-safe, chemically resistant and practical.

Bottles

Bottle designs printed from joined Cura G-code sections to keep the pattern continuous and reduce stringing.

Bruk

A simple polypropylene bottle printed from joined Cura G-code sections. Its folding cap becomes the seal: when the cap bends into position, water stops coming out.

Print files

Baum

A collapsible polypropylene bottle made with the same joined-G-code approach as Bruk. The cap folds to seal, and the body can fold into itself like an accordion when empty.

No-added-sugar cacao bars

Two or three ingredients, no added sugar, and recipes that are easy to understand at a glance.

Shiro

A white cacao-butter bar with only two ingredients and no added sugar: 2/3 milk powder and 1/3 cocoa butter. Creamy, minimal and naturally more paste-like than sugary white bars.

Print files

Stop

The first standalone River cacao bar: vegan, bitter and built around 62% cacao with 38% coconut milk powder. The same rounded 62/38 proportion shapes the bar, while the coconut fat gives it a clean melt-in-the-mouth texture.

Print files

Amara

A bitter milk-cacao bar for people who like dark profiles: 2/3 cacao and 1/3 milk powder, with no added sugar. It lands close to an 80% dark character, but the softening ingredient is milk, not plain sugar.

Print files

Fragile

A three-ingredient cacao bar with no added sugar, designed to arrive broken on purpose. Fragile turns a shipping problem into the format: thinner packaging, less waste and pieces that are meant to be shared.

Print files

Tato

A three-ingredient cacao bar inspired by childhood creamy milk bars, but with cleaner ingredients and no added sugar. Amara and Shiro are the parents; Fragile is half of each; Tato is the next generation, closer to Shiro.
