When designing 3D printed parts that need to fit together, using pins and holes is a common method. However, there are alternative ideas that can improve the fit and strength of your designs. [Slant 3D] explores these ideas in a recent video (link included) that can open up new avenues for your projects.
One option is to chamfer the pins and holes. This allows the object to be printed in different orientations without affecting the fit. Chamfering also makes the features less brittle and provides a broader surface for gluing. Another alternative is using fins and slots, which adds robustness compared to flimsy pins. By chamfering the edges of fins, they can be printed vertically for better strength and easy location without support material.
Implementing these techniques is not much more complicated than traditional pin-and-hole designs, and they are less likely to break and ruin your day. If you want to take it to the next level, consider adding folded techniques to your repertoire. Check out the link to [Slant 3D]’s video and see how you can improve your 3D printing game.
