Prusa i3 MK3 Low Profile Spool Holder

prusaprinters

<p>The standard Prusa i3 MK3 spool holder is almost totally vertical which makes it take up the most possible space in the height direction. I had a height restriction due to the shelf my printer was going to sit on, so I designed this as a way to make it fit.</p> <p>This holder is angled backward allowing the spool to sit 2" lower and just behind / below the top of the frame. See the thumbnail showing a comparison with the original Prusa MK3 spool holder STL and this low profile spool holder.</p> <p>Your filament may rub on the frame using this mod (depending on spool diameter). I recommend either putting a low friction tape on top of the frame or printing a filament guide such as this one: <a href="https://www.prusaprinters.org/prints/1299-filament-guide">https://www.prusaprinters.org/prints/1299-filament-guide</a></p> <p>I have printed this and installed on my MK3 successfully, so far have not had any issues printing parts and having the filament roll off of the spool.</p> <h3>Print instructions</h3><p>Unassociated tags: arm style</p> <h3>Category: 3D Printer Parts Print Settings</h3> <p><strong>Printer:</strong> Prusa i3 MK3</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> .15 mm</p> <p><strong>Infill:</strong> 50%</p> <p><strong>Notes:</strong></p> <p>I sliced with the prusa control program, appeared to be a grid infill. It worked great in ABS, but had to use ABS juice to avoid peel up, as well as a brim (not a full raft).</p>
