Alfawise U30 Pro - Fan Duct with BLTouch

thingiverse

I tried to create for me a new, compact and perfect fitting Fan Duct System, which includes the possibility to attach a BLTouch and my prefered MK3 Fan Duct. Now it's done and i love it more than all other Systems for the original MK8 Hotend, which i created or are available online. It's lightweight, easy to assamble and compact as much as possible. That's why i want to share it with you now after my long-time-tests. This Thingiverse shared Version is having a little bit differend Baseplate than mine, because i don't use the Wheels on X Axis (i'm using a linear Rail on X Axis), so please try the Baseplate at first if it fits with the screw heads of the wheels and tell me, if it fits or what has to be changed. Or you change it by yourself. All other Parts will work nicely. I also changed the Dimensions of the MK3 Duct to make it fit much better around the Hotend and Nozzle and give it a much better airflow to the Print. What you need: - M3 Hex Screws 6mm up to 35mm - M3 Nuts - 5015 Fan (Original Prusa, AliExpress or anything else) - 40mm Fan (i prefer Noctua with a DC Down Step Converter, 12V is more than enough) - Optional BLTouch (i don't give support to install it. Try yourself, there are some manuals online) I recommend to attach always the BLTouch Mount and use my new centred Version of the adjustable X-Axis Endstop: https://www.thingiverse.com/thing:4550036 Link to a working Marlin 1.1.9 with BLTouch v3.1 Support: https://www.reddit.com/r/Longer3d/comments/f1t0b1/lk4_pro_alfawise_u30_pro_bltouch_enabled_marlin/
