Description

PDF

To create the 2 parts for the filament guide, I scaled some parts up so the teeth would be relatively smaller. So the HEX hole was made bigger, the slider with the long slot are made bigger. In the 3MF file the 2 parts with teeth are scaled down again to make the teeth smaller than the original but the slider, HEX hole etc. are back to the original size.

When printing X and Y for slider and Cogwheel should be 90%, please check if sizes are:

Slider: 
X: 67.2 mm (smaller than original)
Y: 65.9 mm (original size)
Z: 8.43 mm (original size)

Cogwheel:
X: 31.93 mm (smaller than original)
Y: 34.26 mm (smaller than original)
Z: 5.6 mm (original size)
