Reversible Ratchet Tool

Well, the title says it all, I modeled up a 3D print I will keep in my toolbox right next to the other ratchets. The video shows its worthiness, a fully capable reversible 3D printed ratchet!

Background:

I printed mine from PLA, because it's easy and I haven't had much good luck with ABS, nor have I bought any PETG... yeah, I'm working with an older model printer. Worst case scenario it breaks, and I would just reprint another from a bio-sourced and biodegradable PLA ;-)

TBH it kicks out some decent torque, I haven't tried to test it to its max yet. That will be down the road, maybe… it's just too cool to intentionally break!

This ratchet accepts different standard screwdriver bits and uses a magnet to hold the bit in place. There are many adapters, like the one I used, to switch over to sockets which as you can see worked pretty well.

If you don't need a ratchet, this thing makes a pretty fun fidget toy! LOL. (just leave the magnet out if it's for the kids… seriously, these things are scary!)

If you like models like this, be sure to leave a ‘LIKE’ and be sure to check out the other models on the page! You might find something you like!

Parts:

Every piece is printed besides the screw bit and the magnet. As mentioned, I used PLA but there are many other materials that would be suitable.

I printed all parts with a 2-3mm wall thickness and 10% gyroid infill for stability.

No supports are needed, my Ender 3 was able…
