Atoma two part replacement rings 12-40mm

prusaprinters

<p>I needed to replace only a few 16mm<strong>*</strong> rings for a notebook from the belgian Atoma book binding system. They are not terribly expensive but since I only needed a few and didn't want to buy a pack of 50 just to have them laying around i thought it would be a nice exercise.&nbsp;</p><p>To be able to print them without support and make all contact areas to the paper smooth and reduce friction in the direction of the movement axis I made it a two part design: you print the ring and the center disc separately and snap fit them together by hand.</p><p>If you have trouble getting the rings to stick on the build plate (as I did) use some glue stick. The contact area is tiny.</p><p>They should be easily printable up to 0.3mm layer height.&nbsp;</p><p>Want to print your custom Atoma compatible cover? <a href="https://www.printables.com/model/251413-atoma-notebook-cover-din-a5">Try this one!</a><br><br><strong>*</strong>16mm is Atoma nomenclature for 17mm outer diameter. They measure at another point point.</p><p>User <a href="https://www.printables.com/social/335874-nick/about">Nick </a>asked if i could do the other diameters to, so i exported them but did NOT test them. You can find them in the <strong>untested diameters</strong>-folder. Feedback would be very appreciated.</p>
