Macramé: Rings and ceiling hook

prusaprinters

<h3>Motivation</h3><p>During the local holidays, my wife wanted to create a macramé and hang it, but all hardware stores were closed, therefore the Prusa Mini+ came to rescue me by allowing me to print the hook and accessory rings.&nbsp;</p><p>I searched in <a href="https://www.printables.com/">Printables.com</a> &nbsp;for something that suits my needs but I could not really find a combo (ring + hook), this gave me the motivation to design them.</p><p>This page include three items:</p><ol><li>A <strong>macramé ring</strong>, (50mm x 10mm)</li><li>A <strong>ceiling hook</strong> and</li><li>An <strong>alternative trapezoid</strong> that can be used instead of a boring ring.</li></ol><p>The hook was copied from a metal hammock hook I have at home, that acts as a double loop preventing the ring to get lose when moving the hammock.</p><ul><li>The hook has a middle hole for securing it to the ceiling, the hole has a 5mm diameter, allowing at least a 10mm diameter screw head.</li><li>Take notice that printing if the part is printed in PLA, you need to be careful not to tight the hook to tight to the ceiling</li></ul><h3>Printing the parts</h3><p>The parts need to be printed for strength, therefore you should use at least 60% infill filling.</p><p>Use preferably a strong and stiff material, like ABS, PET-G or PC. Don't use flexible filaments like Nylon ones, because you won't be able to maintain a trust-able hook. PLA is possible, but be aware PLA can explode without warnings when over-tighten if the part have a low rate infill.</p><p>&nbsp;I used PLA+ because that is what I have :)</p><figure class="image image_resized image-style-align-left" style="width:48.04%;"><img src="https://media.printables.com/media/prints/289783/rich_content/c68a6182-b460-4fe5-ac6e-c04a60a173c5/region.png#%7B%22uuid%22%3A%22950904af-14e2-486f-bc0a-011ce539173b%22%2C%22w%22%3A1256%2C%22h%22%3A800%7D"></figure><p>All parts need to be printed laying in the print bed as in the the left figure, that is laying in the X-Y plane; in this way you gain more strength.</p><p>The same goes for the hook, that need to be printed in the orientation presented in the figure when one of the hooks is completely touching the printing bed.</p><p>Be aware that the hook needs support material for printing the hanging upper hook.</p><p>The rings do not need any support material.</p><p>For a better look, print the parts separately.</p><p><strong>Hope it was not TL;DR</strong></p><p>&nbsp;</p><h3>Last Words</h3><ul><li>I hope you like this model and if you like it, please give it a like, it will make my day and will allow me to get a Prusa mug.</li><li>Don't hesitate to post your makes including comments that can improve the model.</li><li>You are kindly invited to follow me to get updated every time I upload a new model.</li></ul><p>And the most important: Happy printing &amp; Greetings from the Galilee.</p><p>&nbsp;</p>
