Wanhao Duplicator i3 Plus Filament Filter

thingiverse

If you print the initial section without brackets, you can use this with any 1.75 mm filament printer. When printing the segment with brackets, it will fit onto the carriage of the Wanhao duplicator i3 Plus. It might also fit other printers, but I've only tried it on my Di3+. To assemble: Once all parts are printed, gather a few pieces of whatever filter material you prefer (I used a regular sponge found in any kitchen) and insert some into the first section. Next, place more in the second segment, then position the second piece inside the first, and secure it with the lid. You're finished! You might need to adjust the scale of the "Lid" for a perfect fit within the first segment or remove a bit from the flanges using sandpaper. Snug fits like this can vary depending on your printer model.
