Tinker Tuesday for June 16th, 2026

This thread is for anyone working on personal projects to share their progress, and hold themselves somewhat accountable to a group of peers.

Post your project, your progress from last week, and what you hope to accomplish this week.

If you want to be pinged with a reminder asking about your project, let me know, and I'll harass you each week until you cancel the service.

I recommend a mechanical engineering project, and doing the CAD 100% yourself. You'll waste a metric ton of filament on prototypes, but you'll learn a lot. You can look up designs online, but not download STLs.

Depending on your skill set you can try building a simple water pump or a pair of tank treads (arbitrarily complex - you can skip road wheels, suspension, return rollers/idlers, and tension wheels for as long as you like). Sometimes, you'll end up buying a small motor to drive your contraption, but also just building the stuff and turning the moving parts by hand is fun.
