Cap for Kuretake Waterbrush Petit

thingiverse

This cap keeps water inside the Kuretake Waterbrush Petit so you don't need the bottle that comes with it. With this small modification, it's now the most portable waterbrush I've found and fits easily into an Altoids tin. To print the model pictured, use a Makerbot Replicator II. Flip the design so its flat side faces down during printing. It's designed to come off slightly easier than the brush for which it's intended. When using the cap, be aware that applying pressure will force water out along its edges. To avoid this issue, don't compress the cap and store it somewhere secure.
