Building block Arrow

<p>Just in case you can't find that lost bullet/arrow for the building-block cannon for your child, here is an option to replace it…</p><p>Or you can just make your kid's arsenal that much bigger like I did for mine.</p><p>One of my oldest designs!</p><h3>Print instructions</h3><h3>Category: Toy &amp; Game Accessories Print Settings</h3><p><strong>Printer:</strong> Prusa MK3S</p><p><strong>Rafts:</strong> Yes</p><p><strong>Supports:</strong> Yes</p><p><strong>Resolution:</strong> 0.2 mm</p><p><strong>Infill:</strong> 35%</p><p>&nbsp;</p><h3>How I Designed This</h3><p>I used digital calipers on a Duplo arrow, lots of measurements, and 123D Design to assemble the model.</p><p>I found a great way of making my models in 123D Design that allows for modifications in the future should I need them. Binary operations in 123D Design cannot be split in a file that has been saved, then loaded at another time. (Binary operations are "Merge" and "Subtract".) As such, I copy elements before I perform these operations. This results in a file that looks like a step-by-step assembly diagram of the object. Miss a dimension halfway through the process? No problem - adjust the appropriate element and carry it through the steps to get your re-designed object!</p><p>At some point I may include my 123D Design model for reference so you can see this process, though I'm somewhat embarrassed to show my messy workspace! :-)</p>
