Spool Holder for Ikea Ivar shelf system

prusaprinters

<p>I needed a spool holder to put on the side of my IKEA Ivar shelf since the one included in the Prusa Mini kit took up too much desk space.</p><p>I used the 608Z ball bearings from the Prusa Mini spool holder.</p><p>It's attached to the base with a simple keyhole slot so it can be moved around and mounted in different setups.</p><p>Includes two bases, one for side mount on the IKEA Ivar shelf and one generic screw-on base which can be put anywhere.</p><h4>Printing tips</h4><p>Print with PETG or similar for strength, although I can't guarantee your 2 kg spool won't come crashing down mid 30h print.</p><p>Print the arm parts laying down for maximum strength. That's why I've split them through the middle. Mirror the Arm to get the matching part.</p><p>Print 3 Arm Pins. You probably only need one or two, but they are so small anyway.</p><h4>Assembly</h4><p>Look at the exploded view. No screws needed. Maybe a drop of glue if the end cap doesn't get good enough friction fit.</p><p>Print the Ivar Pin if you don't have any spare steel pins. This model is a little shorter than the original steel pin but still sticks out a little bit so you'll be able to take it out.</p><h4>Note</h4><p>This is not a perfect spool holder in any way, so feel free to remix or suggest improvements. It works for me and my setup.</p>
