Open-source tools for conservation fieldwork
Wetewete shares practical, field-tested tools designed to solve real problems in conservation work. All designs are open source — free to download, adapt, and make locally — with field-ready options available for those who need them.
Don’t see the tool you need?
If there’s a field problem you’re wrestling with and nothing here quite fits, get in touch — we might already be working on something similar, or we might just make it next.
Materials & making
Some of our tools are laser cut, others are 3D printed, and some combine both processes. Materials are chosen for practicality, longevity, and local availability — not for mass production.
Wherever possible, Wetewete tools are produced using PLA, a plant-derived bioplastic made from renewable sources. PLA is commonly used in makerspaces because it prints reliably, is durable enough for field tools, and can be industrially composted at end of life.
As much as possible, we also use donated or reclaimed materials. For example, Photarium fronts and Bite Rulers are cut from clear acrylic offcuts that would otherwise go to landfill.
Just as importantly, tools are made on demand, not produced by the thousand. Designs are shared openly so tools can be made locally, reducing freight, packaging, and overproduction.
The goal isn’t to make more things — it’s to make fewer, more useful tools, only when they’re genuinely needed.
