Topic: Filament Protector
When using the filament guide hole in the back of the Solidoodle, it forces the filament to scrape against the frame. This is fine when the filament is being drawn forward, but when it is forced back with +Y movement the frame is sharp enough to scrape pieces of plastic off the filament. Only minor damage, nothing fatal, but there's an easy fix as show in the picture. Just print out a cover for the part of the frame that scrapes against the filament. I've included an STL, but you might want to design your own as it'll be one of the simplest things you've designed and your frame thickness might be different to mine.
You can see that the reel I'm using has a wide diameter. I suspect this is the cause of the problem and the problem might change to the hole itself if a smaller diameter reel is used. So perhaps a grommet for the hole will be necessary for me at a later point.
