Minimal (customizable) motor mounts for various toy quadrotors

thingiverse

Inspired by the exhilarating experience of flying with the Tiny Whoop, this is a minimalist frame replacement for various toy quadrotors that allows for building ultra-lightweight and compact versions of them. Compatible quads include the H8Mini or H101. The "frame" consists of 4 clips that are used to mount motors directly onto the flight controller PCB. To assemble, disassemble your quad, print the four parts, and attach them to the frame using a touch of hot glue. By printing in parallel with disassembling the quad, you can have a super-lightweight quad within approximately 20 minutes. For more information, see these two blog posts: https://skmavs.wordpress.com/2016/08/25/a-superlight-3d-printable-frame-replacement-for-toy-quads/ and https://skmavs.wordpress.com/2016/09/11/super-lightweight-fpv-quads-using-customizable-motor-mounts/. This frame was created using OpenSCAD and is fully customizable. It effortlessly adapts to changes in dimensions, and motor diameters, lengths, etc. can be modified using either the Thingiverse customizer or by opening it in OpenSCAD and generating an STL file. The model source code is also hosted on GitHub for version control and potential collaboration/forking: https://github.com/skohlbr/openscad_models/tree/master/mini_quad_motor_mount. Update August 26, 2016 The sides of the model have been strengthened to make it more robust against breaking. You can inspect these changes using the diff tool on GitHub. Update September 11, 2016 The mount has been significantly improved to be even more resistant to breaking. The OpenSCAD model has also been modified to allow specifying the desired propeller diameter and prop-to-prop distance. The size of the motor mount is then automatically computed. You can view these changes relative to the original upload on GitHub.
