prusaprinters

<p>I really liked the original idea but found some filament did not hold very well - particularly if it was curved. &nbsp;I believe the reliance on very precise tolerances makes it hard to create a groove that will work well with all filament and subtle printer variations. &nbsp;Instead of a groove, this uses a curved tube which provides good holding friction while still accommodating a wide variation in printer and filament tolerances.</p>
