TEVO LM fan shroud 2x 40x15mm fans

thingiverse

It's a super-compact fan shroud for the Tevo LM Delta that uses just two top-quality 40x15mm fans and also mounts the BL touch, requiring it to move slightly to fit the shroud. The original fan set (steel mount, 30mm fan, 2 blowers, and bl touch standoffs) weighs 74 grams, while this one weighs 67 grams, resulting in a small weight reduction. With this setup, you can remove the hotend and change it without removing the fanset, which is a big plus if you have multiple hotends, as I do - I prefer changing nozzle size by having multiple hotends. UPDATE: On October 12th, 2019, I updated the part file STL to remove some material from the part cooling ducts that interfered with the hotend removal. In my print, I just shaved it down a bit with an exacto knife; if you download the file again, you won't need to. UPDATE 2: I updated the part in April 2020 to provide more clearance around the heatbreak heatsink and have been printing these in PETG with no issues. The internal support structures are breaking away easily enough with long-nose pliers. My PLA fan shroud lasted for five months but eventually warped after many high-temperature PETG prints, so I printed one in PETG, which is holding up even better.
