<p>This is a remix of the original triwing LCD knob that comes with the MK3S+.</p> <p>I like the textured surface on the original knob, but dislike the flatness of the pressing area. There are other concave remixes of the same knob, but they do not retain the textured surface pressing area.</p> <p>This knob is composed of 2 pieces. Both pieces are meant to be printed upside down on a textured steel sheet to receive the nice textured surface. The triwing ring has a 0.75mm deep beveled inner lip. When the two pieces are joined, the stem's textured surface is sunken from the ring's lip by 0.75mm. Effectively producing a concave button feel while still retaining the textured pressing area!</p> <h3>Print instructions</h3><p>Layer height: 0.2<br/> Perimeter: 3<br/> Infill: 15%<br/> Material: PLA/PETG<br/> Support: No<br/> Brim: YES on the triwing ring piece</p> <p>The triwing ring piece needs a brim to achieve better adhesion.</p>
