Ender 3 V2 4020 Fan Mount + Laser Mount

thingiverse

Ender 3 V2 mounting system to upgrade to dual quiet 4020 fans and mount a 500 mW laser. I could not find a system to upgrade fans for the V2 and use a laser with they system, so I created one. Parts needed: 2 x 4020 fans 1 x 500 mW laser screws/nuts 3mm (can re purpose items from fans) Used this fan test to check cooling from TeachingTech: https://www.thingiverse.com/thing:3167063 Assembly tip: Counter sink holes on the exhaust side of the part fan. Then use two bolts to attach fan to duct. The other two mount the whole system to the hot end mount. (see picture) I used one bolt to mount to the whole thing to the carrier, same hole that has a screw on the stock fan system. In the other mounting hole I used the center stem from the fan test. Have over 200 hours on the system with no issues. Laser mount needed a screw opposite the original bolt holes. I drilled out a fin gap and used the screw to make threads in the soft aluminum of the laser fins. Let me know what you think and share what you fix.
