Weighted Balisong M4 Fasteners

prusaprinters

<p>Edit: I've reverse-engineered the model into proper STEP files if you want to edit it. Also available on OnShape under the name Balisong Mk II.</p><p>The STEP files are the most up-to-date files and the ones I would recommend using. With PrusaSlicer 2.5, you can now import and use the STEP files directly.&nbsp;</p><p>Print one handle normally and another mirrored. There is both a double ground and single sided blade; the single sided is much easier to print and my recommendation. Fasten together with 2 M4-16mm bolts, 4 M4 washers, and 2 M4 locknuts (you can use normal nuts, but locknuts are recommended). There are spaces in the handles and blade to add M4 nuts for weight.</p><p>The balisong is slightly longer overall than the original, which I thought was a bit short. With all 43 M4 nuts added for weight, it is reasonably heavy, although still nowhere near the weight of my metal bali trainer.</p><p>Total weight:<br>70 grams (2.5 oz) with all nuts added.<br>40 grams (1.5 oz) without any nuts for weight. (100% infill)<br>For comparison, weight of my metal trainer: 170 grams (6 oz).</p><p>You may have to re-orient the STEP files for best printing. There is also a version without any holes for nuts if you just want a quick and easy assembly.</p><p>Fasteners required:<br>2x M4-16mm bolts<br>2x M4 locknuts<br>4x M4 washers<br>43x M4 bolts (for added weight)</p><p>With a bit of silicone lubricant, it flips pretty well: <a href="https://youtu.be/p450AaAcBeI">https://youtu.be/p450AaAcBeI</a></p><figure class="media"><oembed url="https://youtu.be/p450AaAcBeI"></oembed></figure>
