Zen ToolWorks Filament Wheel Extension, Part B
by designrama, published
This extension is designed specifically for 1.75 mm ABS filament sold by Zen ToolWorks on Amazon. It keeps filament from falling off the cardboard wheel.
This piece is 195 mm in dia., it will take up almost every mm on the X axis of M2 bed. I printed it with a two loops skirt, set at 1 mm distance.
It's friction fit, just push it into the center hub. Use a flat head screwdriver to pry it loose for removal.
Before printing this piece, double check center hub dimension with the seller.
