About this 3D model

Ok, this replaces the heatsink+aluminum+wooden piece. on prusa i used a printed part to hold the j head for long time (with cooling). so i figured this should work here too, it has a dual fan mount that give lots of air for both the extruder top and the printed parts. the base part has built it support (0.7 lines designed for 0.35 but should be ok anyways) this should fit jheads but im not sure about makergears since its shorter.
