Extrusion Slider Prototype for 2020, 2030, 2040, profiles. Direct knock off of the Ecoslide system, great for mock ups and so forth. Really not worth making with the price of the bearings being almost the same as the real thing itself, but it could be a fun to play with. It was a project that i have pretty much given up on. Pictures do show i was playing with it on some 20 x 20 mm carbon fiber.
