Ergonomic Chalk Grip

prusaprinters

<p>I never enjoyed writing on a chalkboard because I could never quite grip the chalk well, so I designed this to make creating chalk art MUCH more comfortable :) This model is perfect for teachers or chalk artists, and it also eliminates chalky fingers and hands.</p> <p>(My brother is an excellent chalk artist, and he enjoys this new tool immensely)</p> <p>To assemble:<br/> Slide the chalk into the internal peice, and leave the desired amount above the top. Then slide the outer cylinder down from the top so that the pressure exerted on the four inner grips keeps the chalk in place.</p> <p>This should work with all standard 9mm chalk, and can be scaled if necessary.</p> <h3>Print instructions</h3><p>0.3 mm layer height</p> <p>15 % infill</p> <p>thick shells</p>
