Each one opens a workbench with a live 3D view and an STL download.


A clip-on stop end, plain or with a spout to a hose or downpipe. Seal it with a bead of silicone.


Straight unions, and angle joints from 60° to 180°. One part fits inside and outside corners.


T and Y branches where a side run meets a main run. The floor stays level so water runs through.


Join two different gutters: half round to deepflow, or an older size to today’s 112mm.
Gutter brackets braced back to a screw foot. Sized from the weight of a full gutter.
Next in the set: fittings for round and square downpipe.
Choose a standard gutter or type in your own measurements. The 3D view updates as you go.
A 10mm test piece checks the fit on an offcut in about 15 minutes.
Get a zip with the STL and a note of your settings. Print notes say which way up and what supports.
Every generator runs OpenSCAD in your browser, so nothing is uploaded. Each one is a parametric model: a size change is a setting, not a new design.
Each generator has presets for standard UK 112mm half round and 115mm deepflow gutter, or you can type in your own measurements. Print the 10mm fit test first and try it on an offcut: it takes about 15 minutes.
PETG or ASA. Both cope with sun, rain and frost. PLA softens in summer sun, so avoid it for anything outside.
Every part is sized to print on a 220mm bed, like a Creality Ender V3, so most home printers can print them.
The fittings clip on. Run a bead of exterior silicone in the channel before you fit it, as you would with a plastic gutter fitting from a shop.
It is free and runs in your browser. Each generator runs OpenSCAD locally, so nothing is uploaded and there is nothing to install.
Hi, I'm Will. I make these for jobs around my own house: a gutter that needs a quick fix, or a drawer of cables to tidy. Every part is sized to print on a 220mm bed, like a Creality Ender V3.
