Knurled disc for Infento - adjustable angle WITH stops

thingiverse

This component is indispensable as one pair (one male and one female part) for each multijoint, enabling the construction of a basic hinge. It allows you to limit the rotation angle in both directions. Experimenting with it reveals how to adjust it to your liking. However, the stops are relatively small and positioned on a compact radius, thereby limiting the absolute torque required for stopping. Ideally, orient the twin stops to bear the higher torque loads, as the torque is symmetrically distributed. A stainless steel washer with an inner diameter of 8 and an outer diameter of 16 is necessary to prevent scuffing. The M8x35 bolt paired with the M8 lock nut in the center can be tightened gradually to achieve the desired level of friction. This part was printed in PA using the SLS method. It was produced by www.meltwerk.com. I have included four free hinges without stops and two hinges with stops within this STL file, and they are physically connected via 1x2mm bridges that can be cut with a knife. At the time of printing (late 2019), I paid approximately €18 for this stack of six items. They fit perfectly together.
