Easy-to-Empty Filament Cutter with Optional Mount

prusaprinters

<p>I liked the simplicity of @pomi's filament cutter but wouldn't want to use it without a box a la @wapameeto's.</p><p>However, I noticed that at least at my printer's tolerances, removing the filament cutter from the box to empty it wasn't that easy, a very tight fit. So I spent an hour with Fusion 360 to make some modifications.</p><p>First, I added some “ribs” to the cutter body, to make it easier to grab it for push/pull. Second, I added a cutout to the base of the box so that you can now easily push the actual cutter upward. The cutter top was left unchanged.</p><p><strong>Update:</strong></p><p>6/17/21: Added option to mount it to your enclosure (or other convenient place) using @layershifter's “multiclip mounting system”. Requires a flat-head wood screw (I used a #8 x ¾).</p><p>6/7/21: Regenerated Cutter Body from FreeCad file, to remove artifacts.</p><h3><strong>Material (by @pomi)</strong></h3><ul><li>One segment from snap-off blade 18 mm (<a href="https://www.amazon.com/Stanley-11-301-Quick-Point-Snap-Off-Blades/dp/B000BQY64Y">example</a> 1, <a href="https://www.heureka.cz/?h%5Bfraze%5D=%C4%8Depel+18mm+odlamovac%C3%AD+n%C3%A1hradn%C3%AD+-+10ks&amp;m=f">example</a> 2)</li></ul><figure class="image image-style-align-center image_resized" style="width:347.281px;"><img src="https://media.prusaprinters.org/media/prints/67509/rich_content/621f4363-d438-41aa-805a-17a50d551125/obrazek.png"/></figure><ul><li>2 pieces of screw M3 x 25 mm</li><li>2 pieces of ball pen spring (probably 20 mm length, 4 mm diameter, M3 screw must fit inside)</li></ul><h3><strong>Assembly Instructions (by @pomi)</strong></h3><p>Check video instructions <a href="https://youtu.be/rSI0_ej1MC8">here</a>.</p><ol><li>Print both parts.</li><li>Take one piece of snap-off blade and put it into upper part. Use some pliers to avoid an injury. There is a small mark near blade pocket which shows you where the tip of the blade should be. Additionally you can use super glue to fix it in position.</li><li>Put both screws into the holes.</li><li>Put ball pen springs into the holes.</li><li>Place the upper part on the main body and press it fully.</li><li>Tighten the screws. Screw head should be about 1,5 mm inside head holes. If you will tight them too much it will destroy plate at the upper part.</li><li>Release upper part and check if blade is not visible inside the filament hole. If yes loose the screws little bit.</li></ol><p>Then just slide the cutter assembly into the box. </p><p>Prints fine in PLA and PETG. I printed it at 0.2mm layer height, 3 perimeters. 10% infill, no supports.</p><p><strong>If you like what I'm doing…</strong><br/><strong> </strong><br/>…consider <a href="https://www.buymeacoffee.com/mix579">buying me a coffee</a>.<br/><img alt="orange_img.webp" src="https://media.prusaprinters.org/media/prints/51471/rich_content/8871d2db-9b5f-47c1-a4f7-fd6e73984904/image.png#%7B%22uuid%22%3A%22544551d0-597c-42c7-9c9b-1b838bdd2ace%22%2C%22w%22%3A170%2C%22h%22%3A37%7D"/><br/> </p>
