<p>Filament Sensor Cover for the Prusa i3 MK3S which is adapted to accept a 'reverse bowden tube' to a filament dry box.</p> <p>You have to press fit a small piece of 6mm Festo tube in, see photo. The Festo tube has a inner diameter of 4mm. After that it accepts normal 4mm bowden tube. I do like this solution over a coupling, because it provides easier access when changing filament.</p> <h3>Print instructions</h3><h3><strong>Category: 3D Printer Parts Print Settings</strong></h3> <p><strong>Rafts:</strong> No<br/> <strong>Supports:</strong> No<br/> <strong>Resolution:</strong> 0.2mm<br/> <strong>Infill:</strong> 20%<br/> <strong>Filament:</strong> REAL filament PETG Black<br/> <strong>Notes:</strong></p> <p>No brim. 5 Top/bottom layers.

Lenght 12 mm, outer diameter 10mm, inner diameter 5.8mm. Thats all.</p>
