Longer V-slot wire sneak - ~150 & 300mm

These are really cool - love mbailly's design, just wanted them longer. Did a remix of these to approximately 150mm & 300mm (which does not fit on my bed). Imported into 123D Design, and just duplicated the 75mm and connected end to end. Also, I printed in TPU which makes inserting them into the 2020 very easy.
