Clockmaker - 140mm Fan Fume Extractor

thingiverse

This is the backbone of The Clockmaker: the fume extractors. This part is designed to efficiently channel through a 120mm cornhole into a 130mm square charcoal filter and through a 140mm fan. ## Materials Needed - 1x top piece - 1x base plate, printed upside down - 8x edge triangles - 8x M4 hex nuts - 4x M4 30-35mm screws for the fan mount - 4x M4 screws long enough to attach the base securely - 1x 140mm fan - 1x 130mm square charcoal filter Additionally, you will require: - E6000 or a similar strong adhesive - Proper protection when using the glue and during the curing process - Clamps for secure holding ## Sanding/Glue Prep Steps - Smooth out rough sections on the top and bottom pieces. Since they mate together, a smooth connection is crucial. - Start with 150 grit sandpaper if the surface is uneven or has a lot of roughness to remove. - Move to 220 grit to finish any patches that prevent a good join. - Also ensure that both halves can easily accommodate a filter when joined. ## Gluing Hex Nuts - Wear protective gear, including gloves and a half-mask respirator or equivalent. - Apply a small amount of glue inside the hex nut holes using a toothpick or similar tool. Immediately insert a nut after applying the glue. - Ensure the nut is set before adding more glue and edge pieces. Clamp each edge piece down over the nut carefully but firmly. - Let it set for at least a day if you're using E6000, preferably in an enclosed container or outdoors to ventilate. ## Gluing Halves Together - Wear protective gear again; safety is crucial here. - Place the two halves together with the nuts set under edge pieces and a smooth surface. If both are correct, proceed with gluing. - Thread an M4 screw through each hex nut to remove excess glue that may have entered the threads. - Apply E6000 along the mating edges in a thin layer. - Squish them together, removing any excess glue that comes out. Check for gaps and add more glue as needed. - Clamp your work securely on each corner and let it set for two days. ## Final Steps After everything is glued in place, all that remains is mounting the fan, inserting a filter, and securing the block.
