Tiered Pencil Holder

thingiverse

The Tiered Pencil Holder is a three-level multi-use storage unit designed to hold up to twenty-four pens or pencils in an easily accessible way for students. This versatile holder features an entire separate section on top where you can store whatever you need, making it perfect for classrooms and offices alike. The pencil holes are one inch deep, allowing students to quickly grab the tools they need without having to dig through clutter. The top hole is larger and deeper than the others, making it ideal for storing less frequently used items. The bottom tier of the holder features sixteen pencil-holes, while the middle tier has eight. Meanwhile, the top tier boasts a single large pencil-hole perfect for bigger writing utensils or other tools you want to keep at eye level. The entire design is constructed from a single piece and measures four and a half inches high by five inches wide. This project aims to teach students how to evaluate dimensions of real objects and apply that knowledge while designing the Tiered Pencil Holder. By working on this project, students will learn the importance of creating something useful, rather than just printing toys or trinkets for fun. Making a practical item like a pencil holder helps you appreciate 3D printing in a whole new way. The good news is that anyone can make the Tiered Pencil Holder with basic knowledge of tools and software. The design itself can be used by people of all skill levels, making it an excellent project for beginners or experts alike. Before starting this project, students should have some experience with the following concepts: * Extruding * Intruding * Filleting * Sketching basic shapes They also need to know how to use Inventor (or any other 3D printing application) and be able to print it. Since the dimensions for this project are four and a half inches high by five inches wide, students should ensure their printer can accommodate that size or make adjustments accordingly. Here's how to create the Tiered Pencil Holder: 1. Make a 5x5 square and extrude it one and a half inches upwards. 2. Add .4 inch circles around the edges (16). 3. Create a 3.5x3.5 square in the middle of the first square and extrude it one and a half inches. 4. Put .4 inch circles around the edges (8). 5. Intrude all 24 circles one and a half inches deep. 6. Make a 1.5x1.5 square in the center of the middle tier and extrude it one and a half inches. 7. Create a 1.2 inch circle on the top tier. 8. Intrude the circle three inches deep. 9. Fillet the edges, corners, and rim of holes (you can choose any fillet size you like). 10. Change the color to your liking. Requirements for this project include: * A maximum of sixteen pencil-holes on the bottom tier, with no minimum required. * Up to eight pencil-holes on the middle tier, also with no minimum. * Only one pencil-hole in the top tier. However, you can modify it to be larger if you prefer. By completing this project, students will see significant improvement in their Filleting and real dimension analysis skills. It's not always easy to decide how much to fillet – do you make the entire design rounded or leave it sharp and flat? While working on this project, you'll need to figure out how much fillet is right for your design. Many 3D printing projects don't involve using real objects, but this one requires analyzing dimensions of pencils, pens, or other writing tools. By making this pencil holder, students will learn how big or small they need to make the piece that involves real objects, giving them valuable experience with practical applications of 3D printing.
