Basic Trailer Project: Support Legs

thingiverse

The idea with Basic Trailer Project is to create a custom trailer design using standard parts. It's built with screws and nuts, allowing you to modify, upgrade, repair or disassemble it and build something new. Twist and adjust the objects to fit your printer and print requirements. Here are the support legs, featuring one small motor inside each leg. Switching polarity enables up/down movement. Note that these small legs do not have limit-switches. You can control them using a simple ON-OFF-ON momentary switch, relay, motor controller or microcontroller. I plan to use my homemade Arduino-based digital control system, the same one I use for my truck, forklift and other vehicles. A new video will be released when this project is completed later this winter. Check out this video on how I created some functional support legs on my prototype trailer: https://youtu.be/wwyBKh6TZkA Initially, I was going to attend a truck meeting but had to assemble the trailer using items I had at home due to time constraints. My primary goal is to make every function remote controlled. I don't want to manually connect or disconnect the trailer from the truck. The mounting holes fit double crossmembers from Frame_Parts. For assembly instructions, watch this video: https://youtu.be/g6Y_YFA-o4w Here are the required parts: * 2 x 6V Motor Long Shaft Screw Thread M3x55mm (with various gearbox options and RPMs available) + I'm using a 300 RPM motor but you can choose based on your needs * M3 nuts (square or regular) * Small self-tapping screws for securing the motor in place and middle part
