Sovol SV06 Print Head LED bracket (for back mounted fan modifications)

prusaprinters

Upgrading from the original Sovol parts cooling fan to a back mounted solution using a 5015 fan (or even the stock 4014) enables you to finally see what the print head/nozzle is doing since the fan assembly is no longer in the way. Examples: https://www.thingiverse.com/thing:5803758 https://www.printables.com/model/542760-the-nautilus-sovol-sv06-fan-duct-5015-blower-fan-v However, b/c of the way the extruder stepper motor is mounted way in front of the nozzle, there is no really good way to get the print head area illuminated by mounting LED light bars on the Z-axis or any other location on the printer. So I designed this small bracket to mount a white 5mm LED on the original mounting points and screws of the stock 4014 fan adapter plate to illuminate the printing area directly. It took me some iterations; in fact six altogether when I realized that the original parts cooling fan wasn't mounted in line with the print head, so I had to move the LED hole to the right side of the bracket in the final version. But it was a nice learning experience in SolveSpace 3.1 which is really underrated as a quick, lightweight and free 'old school' CAD program IMO. The LED mount surely can be improved further (or integrated in existing fan duct models which use the front fan mounting points like this one: https://www.thingiverse.com/thing:5964604 ) Power for the LED can be grabbed from the filament runout sensor connector (3-pin JST 1.25 on the right side of the print head PCB - upper connector is 3V3, middle connector is ground) The LED wires can be wound one or two times around the proximity sensor cable to get them out of the way (picture #4). I thought this would be 5V logic so I first mounted a white LED with a resistor, but it's only 3V3, so you can wire in a white LED directly. If you (like me) use a filament runout sensor up on the spool mount you can detach the "DET" connector on the motherboard and make a JST 2.5 to DuPont adaptor and grab the power for the LED from the serial / programming header on top of the mainboard (as seen in the last two pictures). To fix the LED in place I used some black pigmented hot glue, this also reduces the light "backscatter" through the bottom of the LED enclosure. I imagine you could also put a piece of black electrical tape there or use a black sharpie for the same effect. Print Settings Printer Brand: Sovol 3D Printer: Sovol SV06 Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 or 0.28 mm Infill: as you like Filament: generic PLA Notes: should be printable without support, but the LED hole is nicer / more symmetric with "tree"- type support enabled ... aaand the right orientation to print the bracket is of course NOT like displayed by the thingiverse renderer. The mounting plate (with the 2 countersunk screw holes) should be flat on the printer bed. Category: 3D Printer Accessories
