Adjustable LED Mount - Petsfang Ender 3

thingiverse

This is an adjustable LED mount for the Petsfang cooling duct. I used a single 13.5/13.5mm LED cob to provide plenty of light directly to the nozzle of my printer, which works like a charm. The mount can shift from left to right or center and rotate at the same time, staying stable during printing with just one pivot arm. To build this mount, you'll need only a few nuts and bolts. I'll list them all soon. You'll need two 2mm bolts for mounting the LED and two 3mm bolts for the pivoting parts. You might also need two longer 3mm bolts to attach the main part to the fan housing. The mount is a bit bulky, so I'm thinking of trying out other mounting methods. The LED Mount is quite small, making it hard to work with wire guides, so I want to remake the part from scratch. I bought this specific LED because it can run on 21-24v range. I used the spare connections on my PSU and ran a wire to a cheap 3-35v DC PWM. Then I hooked up a .5a fuse on the output and connected that to the LED. The PWM works perfectly for dimming the LED, and my PLA mount isn't melting in the slightest. Since I only run the LED at low power, it doesn't get too hot. However, if I were to max out the power, the LED would need a heatsink to prevent overheating, which could melt the PLA.
