Filament Spool Scale

prusaprinters

<p>Having a scale built into your spool holder is a cool idea. I came across a couple of posts about implementing a load cell and HX711 amplifier to measure spool weights as well as this article - with an Octoprint plugin : <a href="https://hackaday.com/2018/08/10/3d-printers-get-a-fuel-gauge-adding-a-filament-scale-to-octoprint/">https://hackaday.com/2018/08/10/3d-printers-get-a-fuel-gauge-adding-a-filament-scale-to-octoprint/</a></p> <p>I wanted a mount that would work with a Delta Printer - with 2040 linear extrusion and have a handy mount for a reference weight - in this case, 100 grams.</p> <ol> <li>KNACRO HX711 amplifier + 5 kg load cell (4x M4 button screws - two for the top and two for the bottom (I'm guessing that most of the HX711 on <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a> are identical).</li> <li>American Weigh Scales 100g OIML Class M2 Calibration Weight</li> <li>Make sure to tap the holes and not overtighten. The holes are recessed to provide clearance for standard 1kg filament spools.</li> <li>There is a notch in the back for the wires - so if you sleeve, leave a gap. There should be ample clearance for the cable.</li> </ol> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Delta XL</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>200 micron</p></div> <p><strong>Infill:</strong></p> <p>50%</p> <p><strong>Filament:</strong></p> Inland Inland <p>Translucent Magenta</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Both the top and bottom parts were printed with supports and a 4mm brim to ensure that the supports did not pull away (Cura set to 0.3mm distance for supports).
