Small filament spool (⌀200 mm/ 40mm) - upcycling Prusa / 3dimensional spool

prusaprinters

<p>Spools of 3dimensional and Prusa seems to be identical. I have upcycled a 3dimensional spool (⌀200x76).</p><p>Cut the spool in the middle. To get a constant thickness of the spool, I recommend to use a piece of wood which fits to the inner of the spool to guide the saw blade (see picture).</p><ol><li>Make a cut in the middle of the piece of wood&nbsp;</li><li>Clamp the spool in a vice.</li><li>Use a frame saw and put the piece of wood to the rear side of the saw blade.</li><li>Cut the spool.</li><li>In the next step cut off the cylinder of one the two parts. To avoid scratches in the plastic part, mask the saw blade with tape where you do not cut.</li><li>Remove burr and clean the parts from chips.</li><li>Put both spool parts and clamping parts together, allign the parts and drill bores ⌀3mm (4x).</li><li>Remove burr and clean the parts from chips.</li><li>Assemble the small spool using hexagon nuts M3 (4x) and cylinder screws M3x16 (4x).</li></ol><p>To spool rest of filament to your new small spool, you could use my suitable spool winder.</p><p>Link: <a href="https://www.printables.com/de/model/161178-spool-winder-for-spools-with-bore-o38mm-up-to-o64m">Spool winder for spools with bore Ø38mm up to Ø64mm von H3dSprint | Kostenloses STL-Modell herunterladen | Printables.com</a></p>
