Longboard 3D Printed

thingiverse

My parents wouldn't let me buy a long board, so I took matters into my own hands by printing one! The board was designed in Solidworks with two variants: a standard 4-wheel model and an 8-wheel board that's perfect for riding on snow and rain-soaked surfaces. The hinged brackets that hold each pair of wheels make it easy to navigate over curbs, sticks, and rocks without any issues. I'm currently using the 4-wheel design since we're in the middle of summer here in Minnesota. To print all the parts, I used a home-built Rostock Delta printer, switching between ABS and PLA materials. Print Time Estimate: 120-140 hours Printer: DIY Rostock Delta Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 30% Full Honeycomb Notes: To save plastic and reduce the board's mass, I printed it with a 30% infill rate, resulting in a weight of 15 lbs (6.8 kg). How I Designed This As a mechanical engineering student, I'm proficient in Solidworks, so this project was a breeze. It wasn't for a class or assignment; rather, it was just for fun. I started by making rough sketches in my notebook during Calculus and then translated those into a digital sketch on the computer. Designing all the parts took two days, while assembling both models required an additional five hours of work. I'm currently working on designing an all-electric long board, which is the next step in this project. Custom Section Center Steel Rods To provide internal support for the board, I used 5/16" steel drill rods. These rods are also suitable for use as 8mm steel drill rods. Each rod measures 36 inches in length and features threaded ends, which were created using a manual lathe. Nylon thread-locking nuts secure each rod in place. There are six rods altogether.
