Nozzle Wipe

prusaprinters

This is a wipe system I designed for a 20-4040 rail on the Anycubic Kobra (original). After looking at other high end printers I noticed that many of them had a nozzle wipe system made with a harder material. When I start a print my nozzle oozes up to 4cm of extra material before starting during the heating process. I have noticed that this tail ends up hardening on the print bed and may potentially cause further issues with the print if the nozzle hits the tail. The piece I have made is a three part system. There is the mounting hardware, the main body and a silicon top.  The Files include:-The mounting frame- A silicon mold box -M3 hex nut tslot hardware- Spacer kit (5mm sections) To make the print; print at 20% infill with tree supports. The model is designed so the tree supports break away easily. Once the main body and the mold is complete, fill the mold box level to the top with silicon and insert the main body slowly upside down into the mold. The extra cutouts in the main body allow for the excess silicon to create a strong bond with the part. Only after the silicon has FULLY cured remove it from the mold. After that attach it to your printer at the desired location with M3 hardware. The tslot hex nut hardware should be put together on the main body prior to installation as the hex nuts may be a loose(er) fit but will not spin in the hardware.  NOTE: This print is 55mm in total height. If your print head does not make full contact with the wipe it still functions but may not be as affective. The included spacer plate is made to go between the main body and the rails on your printer. Just use the appropriate M3 screws with the plates.  DO NOT OVER TIGHTEN. Over tightening can cause the printed hardware to flex and pull through the rail.  *I have a video of the wipe in action but have no idea if/how i would be able to upload it.
