One of the things I needed to build for my Xdroid project was an armor coating for the Linear Actuators so that they can operate safely outdoors and in all-weather conditions. I know of a few friends that also use actuators in outdoor projects, and figured it might be useful for them and anyone who needs to protect a linear actuator from abuse. The actuators I got were from ServoCity: http://www.servocity.com/html/12v_linear_actuators.html (The Heavy-Duty Variety). The selection of 3 strengths/speeds made it ideal for my project. These models could be adapted easily to other size actuators, I made all of the models by-hand in Blender, and I like to keep pixels/vertices to a minimum. All six models are ready to print, I used my MakerBot Replicator 1-Dual for mine. I plan to make improvements to this design in the future as more needs arise. If you have any questions or comments, all feedback is most welcome! :)Cheers, KrisEach model in my Linear Actuator Armor is designed specifically for 3D printing, and have the minimum-possible vertices/pixels. Each model has a specific orientation that you should print it (i.e. a specific bottom-side), so that each model prints right and looks good. :)I printed this with ABS plastic, but it should be printable in PLA as well. I use a MakerBot Replicator 1-dual for all of my printing, and set my heated platform to 115C (prevents warping, you can set it to whatever works for your printer and plastic combo). Printing:You will need to print the following models to make a complete set of actuator armor:One of the Back-End Motor Tops.One of the Back-End Motor BottomsOne of the Shims (interconnection between forward shaft and back-end motor).One of the Shaft BottomsOne of the Shaft Mid-sections.The numbered-images I uploaded in this thing will walk you through a typical installation process for the armor.TIP: I include my notes below on how to get the models off of a hot build platform without damaging them:When each print is done, leave it on the build platform and let it sit there until the platform cools down to ~60C. The hardware that you'll need is:One linar actuator (any of the 3 Heavy-Duty versions will fit these models): http://www.servocity.com/html/12v_linear_actuators.htmlYou will also need a dozen #6 screws and nuts to secure the parts together, especially on the shim that holds the top and bottom together: http://www.servocity.com/html/6-32_flat_head_phillips_machin.htmlYou will need one of the lightweight mounts for the actuator: http://www.servocity.com/html/actuator_mounts.htmlThanks for reading and printing the Mad Mare Linear Actuator Armor! =) All feedback is welcome!
