Pipe Cleaner
thingiverse
I'm working on my foundation tube right now, and I desperately need a pipe cleaner. A small rock block is getting in the way! I've designed this gadget to incorporate ball bearings for a full 360-degree rotation - it's got eight holes at the back to facilitate that smooth motion, plus three more up front to help me navigate through muddy terrain. Just be careful when attaching the 1/4-20 button head, as I managed to break two parts near the water hole area earlier on. Luckily, a tap came in handy for rethreading the damaged sections.
