Vertex Delta 3D extruder upgrade

thingiverse

The Velleman Vertex Delta 3D K8800 comes with a filament spool holder on its top, laying position, featuring direct filament injection. This design causes the extruder entrance to wear out quickly when using more abrasive filaments such as wood or metal, and it also disrupts the filament end detector that goes haywire, detecting the filament by being pressed down but the filament comes from above. As a result, you'll encounter numerous false positives, even with high-precision filaments. I have a collection of various filament brands and spools, each requiring special storage boxes that I've built to keep them airtight. However, I still needed something to hold the tube in place on the printer itself. To solve this issue, I created a small extension that clips onto the printer, eliminating the need for holes on the top plate. The tube fast plug is intentionally positioned lower than necessary, forcing the filament to enter the extruder a few millimeters below, ensuring the filament detector remains pressed when there's some filament. Since the printer's top plate is only cut and not finished, its width may vary, so make sure to measure it accurately and adjust the model accordingly before printing. My top plate measures 85.87mm in width. To ensure a proper fit, the printed extension is slightly longer than necessary.
