EEW Nano yarn guide
thingiverse
Yarn guides for the EEW nano espinner to prevent snagging and allow filling of the bobbin right to the end. Over time it is likely the yarn will wear through the plastic, but I'm not sure how long this will take. Using a self adhesive metal tape over the surfaces the yarn touches will help with this, but you need to be careful to smooth all edges to prevent snagging, and that's probably more work than just printing another set of guides. Fusion 360 file is included in case you want to mess with it
