CR-10 V2 Filament Runout Sensor - Dual Bowden

thingiverse

**__Ko-Fi:__** [https://ko-fi.com/juliettaexpress](https://ko-fi.com/juliettaexpress) --- Fixed the dimensions of `asan127`'s runout sensor cover to fit the V2. It was REALLY close, however the screw holes holding the PCB in place put the board closer to the filament than the plug compared to the original design, which meant that it was always activated. I also noticed that the hole for the wheel was weirdly smaller than the filament tunnel itself, so I threw in a 256-sided cylinder in Blender and did a boolean cut so that the upper-most part of the cylinder is the same exact height as the tunnel for the filament itself. Simple tweaks, took me about 15 minutes to fix overall, and a few iterations. This might just be a different version of the same sensor though, Creality is kinda known for their "rolling changes without warning" mentality, or even just a different PCB design that moved the mounting holes. Wouldn't surprise me to put it that way. I did try printing this with a 0.04 layer height to make the curves MUCH nicer, but it wound up being pretty fragile or I'd have kept it. Might have been better for me to bump the shells up to a full 2mm rather than keep it at five layers, but given how much cracking I heard as I was putting the screws in, I don't know that going below 0.2 is a good idea at all, so I left it there. I do plan on throwing a TriangleLabs BMG v2.0 onto my CR-10 V2, so I'll need a riser at that point. I might revisit the design and make the tunnel thick enough to use bowden tubes with pass-through bowden connectors instead of the bump-stop ones that PC4-M6 provides so that the contact with the actual filament of the casing is minimal, if there at all, and it's mostly bowden pass-through. The extra height needed for the BMG might allow for the wider thread needed for it, but I didn't want to mess with it quite yet. Infill doesn't matter beyond aestethics. Looks absolutely *banger* in Smoke PLA with three shells though, the diffuse appearance makes it *far* more visible to me. The increased surface area means I can see it from a distance, and it's less blinding to boot. This is remixed from a Creative Commons Attribution non-sharealike, I don't actually need any credit for this myself, the STL is barely changed. Credit `asan127` in full for this.
