parts to make a Lego JCB telehandler

I have been making a Lego Telehandler for my Lego layout in my basement and I needed a 3 section boom that was minifigure scale and also some attachments. I then decided to add hydraulic cylinder housings that you push an axle into and friction holds it while still allowing you to manually move it in and out. the attachments are fastened to the boom via a quick connect system that works by first hooking the top bar into the semicircular cutout and then pushing the pin through the bottom hole. this is a strong and easy connection to make and also prints well. you will need a printer of a bed size of at least 256x256mm.
