Sturdy Di3 v2.1 bracket for Thorped fan duct
Description
A somewhat overengineered bracket to attach Thorped's [WANHAO i3 Fan duct](https://www.thingiverse.com/thing:1246425) to the X carriage of a version 2.1 Monoprice Maker Select / Wanhao Duplicator i3. Design goals: - Attach to X carriage without requiring any drilling/tapping - Reduce torque on bottom bearing by attaching to both top and bottom bearings of X carriage - Provide clearance for larger custom X axis belt tensioners - Don't block the air intake of the radial fan - Print without slicer-added supports (a few twist-off supports are built in to recessed areas on the bottom of the print) This bracket is designed specifically for this hardware version of this printer, and probably won't fit anything else. The STL file for the fan duct that attaches to this bracket can be found on Thorped's [WANHAO i3 Fan duct](https://www.thingiverse.com/thing:1246425) page and is called "Wanhao fan duct". Required hardware: - (2) M3 x 10mm bolts - (2) M3 nuts - (2) M4 x 35mm bolts for top of bracket - (2) M4 x 25 or 30mm bolts for bottom of bracket* - (2) M4 x 25mm bolts to attach the fan - (4) M4 nuts (2 for top of bracket, 2 for fan) *From the comments, different users report different lengths (25 vs 30mm) are appropriate for the bottom bolt. This could be a difference in measurement techniques - when buying new bolts, note that measurements on the packaging typically are for the threaded portion only and don't include the head. Thanks is due to the contributors in the comments (tehgreedo and rcollins927) for bolt measurement feedback - I neglected to measure those in my installation, as I cut them to fit from 60mm M4 bolts I had lying around. Other mods This Thing is part of a set of mods I've designed for this printer - here's the rest of the set, I hope you find them useful: This Thing is part of a set of mods I've designed for Wanhao i3 and its clones.
