Purge bucket for Ender 3

thingiverse

I added a 3DChameleon Mk2 to my Ender 3 so I can print in 4 colors and use PVA filament as a support material. For multi material printing I prefer a purge bucket over a purge tower because it uses less waste and takes up no printing space. My Ender 3 has a 235mm print bed but the X axis will go up to 250 so I set the firmware to X249 so it does not hit at the far end. At X249 the nozzle is inside the bucket when it purges. For the wiper I used a piece of a silicon trivet. 2 sides are needed due to the limited space. I put some tape on the inside to keep the hot filament from sticking.
