EDIT 3/2020 I've decided to discontinue further updates for this v2 project. Instead, I recommend checking out the latest version available at the following link: https://www.thingiverse.com/thing:4139663 Please note that I don't adjust my printer settings, so make sure your XY compensation is set correctly. The new design includes an optional 35mm fan that can blow air upwards and potentially even suck heat away from the motors! It also features 12mm to 16mm motor mount spacing, a significant improvement over v2's limited support for only 18xx size motors and below. You can use this design with up to 5-inch props and take advantage of 30.5mm or 20mm triple stack spacing, including a wip 2mm mount hole adapter. The electronics cover is included, but the battery wire holes are still in progress - you can either drill your own or create them using spare parts. I've optimized the design to use only 4 x 10mm M3 bolts and 4 nuts for cap mounts. Be sure to apply blue loctite to all bolts. The design also supports 28mm cameras with 2mm bolts and includes a vtx antenna mount. Please keep in mind that I'm still waiting for my parts to arrive, so the fit might be uncertain. I welcome any constructive feedback or input you may have.
