We need to create a spare part for the chair, a knob that will hold the screw in place, plus it will enable me to tighten the screw by hand. I decided to fix this problem, quickly and efficiently.įast forward about two years, and here I am, coming up with a plan! The plan But the screw itself is too thin and doesn’t hold the back of the chair properly. To be honest, I don’t really care about visual aesthetics, because you can’t usually see the underside of the chair anyway.
The plastic knob on the underside of one of our office chairs broke in half, so now only a bare screw remains: The underside of a cheap office chair usually looks like this: And don’t worry, it’s not that difficult! The problem For instance, you can create a general shape, like a gear, and then you can easily change its size or number of its teeth just by changing a variable. What’s so great about this? One of the biggest benefits is that OpenSCAD allows you to parameterize items. This freeware application might seem a bit frightening to new users because it takes a different approach to 3D modeling – it allows you to create 3D objects by programming. However, this time we won’t be using Fusion360 or similar software.

What if you need a custom-made model? Today, we’ll look at how to tackle a quite common problem: creating a spare part from scratch. How do you 3D print something? Well, that’s easy: get an STL model, load it into a slicer app, generate a G-code, upload it to a 3D printer and that’s it! But what if you can’t find the desired STL file in an online repository.
