prusaprinters

<p>Tone and Volume Knobs for a Supro/National/Valco style lap steel guitar, perhaps other normal style guitars. This part is designed for a "24" "fine" splined split shaft pot, however could be reworked for the 18 spline type, the part that goes over the potentiometer is a separate object and overlaid on the knob model itself. I've included the .blend file in case you want to add any different lettering.</p> <p>This part is not a 1:1 replica of the original knobs since I don't have any to compare against. In particular the letter and marker dots are not the exact size, and I do not know if I got the same number of little grips up the sides of them. I was working off of photos of the originals and was unable to find anything high enough resolution/the right angle to get proper dimensions for these.</p> <p>If you're looking for a replacement that goes onto the original pot shafts (1/4" round, held in place with a set screw then check:</p> <p><a href="https://daviesmolding.com/catalog/series/knobs/control/?SeriesID=1450">https://daviesmolding.com/catalog/series/knobs/control/?SeriesID=1450</a></p> <p>(It looks like these are nearly identical to what are getting sold on Reverb and other sites)</p> <p><a href="https://www.mouser.com/ProductDetail/Davies-Molding/1475-PLAIN-HOLE-W-SET-SCREW">https://www.mouser.com/ProductDetail/Davies-Molding/1475-PLAIN-HOLE-W-SET-SCREW</a></p> <p>(These are larger dimensions I believe)</p> <p>This part was made out of a desire to have something that retains the original look, but with volume and treble marked, and able to fit onto a modern standard guitar pot.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Anycubic Predator</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>.05 mm</p></div> <p><strong>Infill:</strong></p> <p>n/a</p> <p><strong>Filament:</strong></p> novamaker PLA+ <p>black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Will upload photos of finished product. Also used CURA to slice and enabled "Adaptive Layers" experimental feature to make the tops of the knobs easier to scrape/sand to smoothness, which helps considerably if you are using FDM as opposed to SLA/DLP.</p></div> Post-Printing ============= <p>The marker dot and letters are inset .5mm and can be filled with crayon wax/paint or if you're fancy and have a dual extruder go ahead and remix with that part in a different color :-)</p> <p>For this I blobbed in some parchment colored acrylic paint and then scraped the extra paint and striations on the top mostly flush with a single edge razor blade. It could probably use some wet sanding on the top as well but that's pretty much it. I imagine this part would also benefit from being done in resin.</p> </p></p> Category: Music
