e3d-lite6 cooling tube for Fusebox 1.4

thingiverse

I was having clogging issues due to the hot end becoming too warm. In order to solve this I designed a cooling tube to improve airflow to the cooling fins of the hot end. Specifically made to fit the e3d-lite6 hotend and a 40x40mm fan, the cabling of the hot end should go around the carriage; if you guide it towards the back side of the printer, it shouldn't get in the way of any parts. I recommend using some tape (I used electrical tape) to close any seam between the fan and the duct. Print Settings Printer: FuseBox 1.4 Supports: Yes Resolution: 0.2mm Infill: It doesn't matter as the part is very thin. Notes: I printed this at 0.2mm because of cooling issues I couldn't print at any other resolution reliably; this might be different for your printer. A brim is advisable to prevent the part from falling over while printing. 5 sept: Support removal can be tricky for the duct, I haven't found a 100% working solution for placement and design yet due to size constraints within the carriage. 5 sept: Added a slightly modified carriage design. It's based on the "newcarriage" made by AlexY. The main change is removing a small ridge in the center hole; with this you don't need to remove it manually after printing. The duct will still fit the original one with some sanding. As per the instructions of the original carriage, it should be printed with 3 perimeters and 30% infill. Post-Printing Assembly Instructions First mount the hot end, then slide this part over it from the top. It should fit right between the hot end and the carriage on the back side of the carriage (the side facing the rear of the printer). You may need to remove a slight bit of material from the carriage to fit it, as the fit is rather tight. No screws or tape are required to hold it in place because it takes a little force to put it in and pull it out.
