Because the enclosure I build: https://forum.duet3d.com/topic/8397/tevo-little-monster-duetwifi-touch7-my-conversion/7 The good work of Thomas was too large to fit within the structure, so I designed something smaller and more compact instead. We don't need any glue to put it together; the small cylinder simply fits inside the larger one from Thomas. I used some scotch tape as a gasket, which allows the fan to interlock securely and be removed easily. Here are some tips: RESIZE THE SLICING TO 102-103% TO REDUCE THE GAP BETWEEN THE TWO CYLINDERS. I sliced the part using CURA 4.1. Material: ApolloX ASA from FormFutura, printed at 220 degrees with a bed temperature of 115 degrees. Layer height: 0.1 mm, nozzle diameter: 0.4 mm (E3D original volcano). No support material used. I applied BRIM for bed adhesion on the outside and inside of the piece. I used white glue mixed with sugar and water to stick the part onto the plate. I printed without a fan at all. Line width: 0.4 mm, infill density: 100%. I purchased the quietest fan available - Noctua. However, your settings will depend on your specific hardware setup and calibration. The outside shape turned out perfectly, but there were some tiny imperfections inside due to the hat coming from the glass. I would have used sandpaper to smooth out the surface for better airflow. Using my Dremel tool clone, I drilled three holes (point n2) and cut a corner to improve the visual appearance of the nozzle. To bring the fan closer, I lowered the original Thomas cylinder using a hacksaw, aligning it with the screw holes.
