Prusa i3 MK3 MK3S 1.75mm Filament Feed Guide for 3D Printer Enclosure

prusaprinters

<p>I designed this 3D Printer 1.75mm Filament Feed Guide for my Prusa i3 MK3 after building a two tier IKEA Lack Table based enclosure designed to store a pair of printers. Due to the twin storey configuration it wasn't possible to feed the filament from above the bottom printer, so I decided to design a filament feed guide that would allow the filament spool to sit alongside the printer.</p><p>As part of the design I wanted to ensure the filament could be fed and changed easily, without getting snagged or suffering from excessive friction/drag during prints (that could lead to under extrusion or unwanted stress on the extruder motor etc). I also wanted the feeder to be easily attached with no tools or modifications needed and to remain firmly in place throughout use. This filament feeder is the result which I've been using for a few years with various filaments including PLA, ABS, PETG, ASA and Flexibles, all with total success.</p><p>The kit comprises of 3 printed parts and a 15cm length of 4mm O.D. (outer diameter) teflon tube (purchased separately and cut to size).</p><p>Simply push one end of the teflon tube all the way into the head of the upper feed arm and the other end into the circular well of the flay mounting bracket.</p><p>Clip the filament feed arm onto the right side of the top of the printer's metal frame and, being careful of the clips, mount the flat base onto the top of the right hand Z axis into the hexagonal hole, rotating the teflon tube as necessary.</p><p>Finally slip the hexagonal locking key into the base which keeps it mounted in position.</p><p>Designed for the MK3 and MK3S.</p><p>=====</p><p>If you like this model please click the 'Like' button.</p><p>Also I'm super happy to see photo's of people's makes, so please come back and share a picture of your print. :-D</p><p>And if you found my design helpful or it saved you some $$$ I'm always grateful for a small donation that will help fuel future designs by way of a cup of coffee. Thank you.</p><p>=====</p><p>This model is not to be uploaded or sold in any form, or modified, and is intended for personal use only.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p>&nbsp;</p><p><strong>Printer:&nbsp;</strong></p><p>i3 MK3</p><p><strong>Rafts:</strong></p><p>&nbsp;</p><p>No</p><p>&nbsp;</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Resolution:</strong></p><p>&nbsp;</p><p>0.15mm</p><p>&nbsp;</p><p><strong>Infill:&nbsp;</strong></p><p>50%</p><p><br><strong>Filament:</strong><br>Hobbying Premium PETG Black&nbsp;<br>&nbsp;</p><p><strong>Notes:&nbsp;</strong></p><p>No Supports Needed. Print the top arm face down with the feed tube pointing toward the sky. Print the mount and locking key flat side down.</p><p>PETG (from various manufacturers) was used for the print of these parts which all fit my machine perfectly. PLA will likely work well too (though not be as strong), whereas ABS will potentially shrink on cooling and so may require increasing in size slightly before print in order for the parts to fit correctly.</p><p>&nbsp;</p><h3>Post-Printing</h3><p>After a little testing with various filament materials I found the 4mm O.D. 15cm length of Teflon Tube worked best with in internal diameter of 3mm. This allows all filaments to slip through easily without any friction. With care taken Teflon Tube can be cut easily with a craft knife.</p><p>=====</p><p>Please note, the model files that you print may look ever so slightly different to the printed versions in the included photographs that may show previous iterations of the design.
