My 3D printing days began in 2013. Like many others in the RepRap community I started out with a RepStrap (term coined by the community) because I built it with parts that I salvaged from other things. I started by finding old inkjet printers for on Craigslist for very cheap or even free. I took as many as I could get and took them all apart searching for smooth hardened steel rods, brass bushings for linear motion, and stepper motors for driving the axes. After finding enough parts, I built a typical moving bed frame out of 8020 1" t-slot profile. It was a decent printer but was very limited by speed and since it was all cobbled together from wood parts it wasn't the most accurate. Wanting better, I started designing my own CoreXY printer because I liked the idea of the print bed not moving in the X and Y axes. I designed it to be mostly printable and lasercut-able. I re-purposed some of the frame pieces from my old printer in this design. After putting it all together,...

The 1680mm size Skywalker is a great plane and I have read lots of good things about its little brother. So I decided to try my hand at building a Mini Skywalker. Scaled to about 95% First, I found some good pictures for getting the dimensions and general design. Then, I used the pictures with a few known dimensions to find the rest of them and I drew out the most important parts. I used 6mm Depron with for most of it and some 1" EPS to thicken the nose for space to put my battery and other components. For the wing, I did a fold over style Armin-type airfoil with packing tape on one side. This was my first wing built this way so it didn't turn out great but I think it will do the job. I put a small carbon spar at about 1/3 of the chord.
