Lego Minifigure Hand Chalk Holder

thingiverse

This is a practical container for up to 10 whiteboard markers, modeled after a Lego Minifigure's hand. When printed at its standard size, it can hold markers with diameters of 10mm. If you print larger or smaller markers, adjust the scale accordingly; e.g., use a factor of 1.2 if your markers are 12mm in diameter (or 0.8 for 8mm markers). Print Settings: Printer: Witbox Rafts: No Supports: Yes Resolution: 0.2 mm Infill: 40 % How I Designed This: To create this, you need minimal parts. Begin by building the hand using cylinders and a quadrangular prism to form the hand's opening. Use a torus to anchor the hands, another at the bottom for stability, and an extruded circle for the base. Finally, round off all edges to your preference. Project: Lego Minifigure Hand Marker Holder Objectives: Design a useful item for the classroom. Create something with just rounded shapes (and one prism). Familiarize yourself with basic CAD operations. Audiences: Everyone seeking quick creation of objects that look good. This project is especially beneficial for students, providing them a practical tool to use in class. Preparation: Students should be familiar with computers and their chosen CAD software. Mice are helpful for CAD work, but it's recommended they have some prior experience or a teacher's assistance. Working alone can be challenging without previous knowledge; hence, group collaboration is encouraged. A 3D printer is necessary for this project. Steps: Brainstorm ideas for objects that could aid classroom learning. Select one item and discuss its appearance with your group. Verify if your CAD software can handle various shapes (prisms, pyramids, cylinders). Begin creating the chosen object in your CAD software. If you need help, consult with a teacher or fellow student. Print your design for aesthetic appeal. Results: By completing this project, students should gain two main skills: using rounded objects effectively and operating simple extrusions. You can stock 10 markers (5 white and 5 colored) per week, replacing them every Monday morning to ensure there's always enough chalk for your classes.
