RainnWorks 3D models

Parametric 3D-printable models in OpenSCAD. Free to print yourself, or configure and order one at rainn.works/models.

The models

Each model is one folder: the OpenSCAD source, ready-made STL and 3MF files in export/, renders in previews/, and a README with how to print it, which parameters matter, how it works and its limits.

	Cake topper A three-line "Happy Birthday" cake topper with a big inlaid background number, printed in four colours with two posts. Configure and order one
	Portable-AC door bulkhead A threaded fitting that takes a portable air conditioner's exhaust hose through a hole drilled in a door, with a hose clamp, caps and a bug vent. Configure and order one
	Glass name tag A script name tag that clips over a wine glass rim, placed by measured ink so no letter prints loose or touches the glass. Configure and order one
	Glass name tag, back clip The glass name tag with its clip turned out of the letter plane, so the name hangs on the front of the glass facing the room. Configure and order one
	Hall of Fame sign A 300 mm "Hall of Fame" script sign for a mirror, printed as three flat words and placed with a 1:1 paper template. Configure and order one
	Play-Doh pot organiser A stackable tray that hangs each Play-Doh pot by its own lip, so a loaded tower lifts as one and costs no extra height. Configure and order one
	Ruffle piping nozzle A printable ruffle piping nozzle traced from the Birkmann #122, with a screw-on coupler so you can swap tips without emptying the bag. Configure and order one
	Van air-filter cap A tapered press-fit weather cap that keeps rain off a horizontally mounted van air filter, with diamond vents on its lower side. Configure and order one
	XIAO + Wio-SX1262 enclosure A support-free, screw-free printed case for a Seeed XIAO ESP32-S3 and Wio-SX1262 radio bridge, with both supplied FPC antennas inside. Configure and order one

Print them yourself, or order one

Every model here is free to print for yourself. Open a model's folder, set its parameters in OpenSCAD (or MakerWorld's parametric maker) and print it.

Or configure it in the browser at rainn.works/models and order it printed from RainnWorks. Ordering sends us your exact settings by email. We ship worldwide and agree shipping and cost with you before anything is printed.

Build from source

Each folder has a Makefile. make rebuilds that model's previews and exports from its source, and its README lists the other targets (tests, checks, plates). You need OpenSCAD on your PATH. Some models also need Python 3 or the BOSL2 library; their READMEs say which.

The README images are built from the committed renders, not from the models:

python3 assets/src/render.py   # needs Pillow and rsvg-convert

It writes assets/hero.png, assets/icon-1024.png and each model's assets/hero.png, from the SVG sources in assets/src/ and each model's assets/src/.
