Redesigned topcover

thingiverse

I decided to put some new life in my K8400 Vertex by upgrading to the E3DV6 hotend (twin). I really liked the original design of Bo_Ris and went for that. Everything went OK though with the latest E3DV6 you cannot use the original nozzles of the Vertex anymore so I decided to use the E3DV6 0.4 mm nozzles instead. The only real problem I had was with the original topcover which was difficult to mount, mainly because of the limited space at the sides and the assembly on the fan. So I took the topcover design from the .STEP file with Fusion. There I enlarged the width of the cover, filled two of the holes for the bolts and, jut for fun' put some text on the front of the cover. To mount it you can use two shorter M3 bolts directly on the (40x40x20) fan. Once tightened the fan is already well fixed and in place. Now place the new topcover, which shifts easily in place, and use the longer M3 bolts to fix it on the fan. I printed the new topcover already with the new hotends and the result was fine.
