Wanhao Duplicator 4X - Top cover plate for MK9 extruder

cults3d

This week I upgraded my MK8 extruder on my Wanhao Duplicator 4X to an MK9 version, with a kit purchased from ultimate3dprintingstore.com. Unfortunately when I tried to put the top cover plate on, I noticed it no longer fit! The new extruder has a "bulge" at the top that prevents the original plate from attaching properly, resulting in a loose piece that might fall during printing. The part (sold separately) costs $15 for plastic and $30 for aluminum. So I decided to search Thingiverse and although I found many innovative designs, none of them could fit my 3D printer. The holes for the screws and filament guides didn't line up properly or the size was too big. In the end I made my own and am sharing it in hopes that it might help someone in a similar situation. If you need this part for a quick replacement use the following settings: ABS, 10% infill No raft, no supports Bed temperature: 110°C 5 solid top layers 2 outer shells It should print in an hour or less with enough strength to be reliable. If you want to use it as a permanent part of your printer increase the infill to 20% and the solid layers to 10 both in the top and the bottom.
