I have been experimenting with 3D printing yoyos recently. I have “successfully” tapped the halves by taking a spare axle I have, pressing kinda hard, and screwing it in but it introduces a lot of vibe because I can’t screw it in straight. What is a good way to tap the halves as straight as possible so it has little to no vibe? Thanks
What about accommodating an area for lock nuts in your cad, so you could just insert them?
I hadn’t thought of that
I use 12mm or 16mm m4 bolts with hex nuts. Lowe’s has them, but you could probably find them online. Just make a spot for them to sit in so it can be tightened. Threaded inserts are another option but I haven’t tried that yet.
Hopefully the picture shows what I mean. The prints I’ve made came out kinda bad so it may not be super clear
If you know the thread pitch and size you could just model it into object you’re printing. Granted, it’s not great for long term / high use, but it’ll work and can work quite well. Another option like mentioned above would be to use lock nuts or heat inserts. Heat-set inserts are a fantastic option because you melt them in place and the mechanical hold is much greater than printed threads.
