Muffin Fan Holders

thingiverse

**General Description** Two customizable muffin fan holders that are part of a system of fans that direct air from a 3D printer up and out of a skylight window. The first part is an L-shaped bracket that may be used in the corner of a window frame. The second part is a full rectangular enclosure with an opening on top. Both parts can be printed as a single piece or in two halfs to minimize supports. The included STLs are for 60mm and 90mm muffin fan holders. Holders for other sized fans can be generated using the included .scad file and the OpenSCAD customizer. **Customizable Parameters** Fan dimensions L-bracket or full enclosure with a opening on top Generate full part, bottom half, or top half **Gluing the Holder Halves** Gluing the holder halves is optional, the screws that mount fan to holders will hold halves together in correct position. I used medium CA on the 60mm L-bracket (pictured), but not on the enclosure (also pictured). **Fasteners** \#8-32 x 1" nylon screws (#8 ~= 4mm) for securing muffin fan to holder M3 x 10mm screw, nut, and T-nut to secure holder to 3D printer **Other Thingiverse Things Used** Thing 625905 "OpenSCAD parametric fan model" by GelatinousSlime for fit check Thing 3050607 "T-nut M3 drop-in rotating V-Slot" by DaVinci2000 for attaching holders to 3D printer frame
