![]() ![]() ![]() One of the great things about designing models in OpenSCAD is that they are parametric, which means that you can change features of the model very easily by modifying the values of its input variables. You can read about this at the MakerHome tutorial Designing a Penny Trap with OpenSCAD, and take a look at the actual OpenSCAD code.ĭesigning an Interactive Coin Trap Model for Thingiverse Customizerįinally, we can extend our OpenSCAD model to make it customizable for other users that want to create different-sized coin traps. With the code-based design software OpenSCAD, you can use simple code to place, rotate, and take “differences” of objects to make the Penny Trap design. Alternately, you can now import basic Tinkercad models into Fusion 360 and then apply features such as Fillets you can read more about that process at the Tinkercad Blog and at our previous article Filament Samples and Customizability. Just by pressing the “F” key you can access the Fillet tool, which you can use to round the edges of your model as much as you like:įusion 360 has a steeper learning curve than Tinkercad, but it pays to learn it so that you can make use of advanced tools like Fillets, Lofts, and Sweeps. In Fusion 360 you can easily Create a Cube, move it to the origin, and then Create a Sphere that cuts through the Cube: Getting started witih Fusion 360 is easier than you think if you’re interested in getting started then I suggest the excellent CAD for Newbies videos by Maker’s Muse. But if you know how to use the more advanced modeling software Fusion 360 then that process is much easier. With a little work you can use Tinkercad to make nice rounded edges on your model, even in the “portholes” of the Penny trap. You can read about this at the MakerHome tutorial Designing a Penny Trap with Tinkercad, and tinker with the model itself in Tinkercad. ![]() Designing a Penny Trap with Tinkercadįirst, with Tinkercad, you can drag and drop shapes and cut out “holes” from some shapes using other shapes. Those happen to be exactly the same four design tools our students will learn about, so this is kind of a preview of the whole arc of the semester. In this article we’ll walk through how to create this model in Tinkercad, Fusion 360, OpenSCAD, and the Thingiverse Customizer. ![]() The Penny Trap is a very simple model, and you could make it in lots of different design programs. The “right time” is when the model is about 60% or 70% printed this ensures that the penny will sit below the printing height of the nozzle, which will help us not damage the machines! The answer is that we’ll pause the prints at the right time and drop the penny in, then let the 3D printer continue printing above and around the penny. This model is a good illustration of a design that is possible with 3D-printing but would be impossible with standard subtractive manufacturing methods such as milling. As usual, our first-day 3D print will be a Penny Trap. Spring semester is coming and we’ll be teaching a introductory class on 3D printing and design. ![]()
