EDC Container Box Capsule + O Ring

prusaprinters

<p>--– <i>Printed O-Rings (TPU)</i>---</p><p>I &nbsp;do <strong>not </strong>recommend using self-printed TPU O-rings. In my tests, these performed worse than original ones. But they are still better than no O-Ring. But only if you <strong>use very very soft TPU</strong>! I have 2 versions. One O-Ring to put into the lid and one for the outer O-Ring version. (Keeps the threads dry too). Don´t combine both O-Rings because that might reduce the sealing capability!</p><p>&nbsp;</p><p><i>--- Small hint in case of fitting problems ---</i></p><p><i>Some have problems with the lid being too small. This can happen if the printer is not set up well and larger tolerances are required. You can separate the individual parts of the .stl in your slicer and enlarge the cover a little to solve the problem.</i><br><i>(Google "your slicer name" + "separate objects" or "splitting model")</i></p><p>&nbsp;</p><p><i>--The POWER of Scale!--</i></p><p><i>You may <strong>scale </strong>the Container to your needs! For example bigger for more stuff or smaller to transport some pills, ear protection or sth. else on your <strong>keychain</strong>. try it out yourself! But keep in mind that the container needs to stay round and the needed O-rings will change their size too (if you print a version with O-Rings). Also watch the printed perimeters in your slicer! &nbsp;(at least 2 will be needed to giv it protection vs. water!)&nbsp;</i></p><p><br><i>But don´t worry too much! Simply test it out yourself!</i></p><p>&nbsp;</p><p>Inner Volumes as base to scale the container:</p><p>Large: 69 mm hight x 19 mm diameter.</p><p>Small: 36 mm hight x 19 mm diameter.</p><p><i>---------------------------------------------------------------------------------------------</i></p><p>After downloading and using a nice EDC Container I instantly wanted to create my own version :)</p><p>I designed it to be waterproof, slim profile and it should be able to contain a 18650 battery. Also it should be able to secure it with a lanyard/ rope, be very stable and have a smooth inner tube.</p><p>I dunked them in water and none of these containers leaked air. But of course that is not enough for me :) So I put them into my vacuum chamber and tested the container to their limits!</p><p><i>I printed different versions with PLA, PETG, TPU, PA-CF.</i></p><p>2 of my versions need an O Ring EDC InRing: 17 mm x 2,5 mm EDC OutRing: 17-22,5 x 2,5 mm.</p><ul><li><strong>EDC OutRing</strong> ---&gt; Is the only Container which did not load any water and is even air tight.</li><li><strong>EDC InRing</strong> ---&gt; Didn´t load water with half vacuum test but took a little water with full vacuum.</li><li><strong>EDC NoRing </strong>---&gt; Did load water with half vacuum.</li><li>Original ----&gt; Same as No Ring but this version takes Air/ Water even through the roughened areas.</li></ul><p>So the tested Order of Sealing quality is EDC Out &gt; EDC In &gt; EDC No &gt; Original</p><p>I hope you like my Design of an EDC Container. I´m open to suggestions for improvement and would love to hear some feedback :)</p><p>Have fun and keep printin!</p><p>&nbsp;</p><p><strong>Print recommendations</strong>: I printed the 2 parts (lid and body) sequentially with 2-3 perimeter and 100% Infill.&nbsp;</p><p>&nbsp;</p><p>Tipp1: Check if your <strong>flow rate </strong>is <strong>correctly adjusted! </strong>If not the print might not be air/water tight.</p><p>&nbsp;</p><p>Tipp2: Add some lubricant (beeswax, graphite or paraffine for example) to the threads to make them work even better!</p><p>&nbsp;</p><p><i>Additional for the NoRing Version: If you heat up the inside of the cap carefully and then screw the two pieces together it will create a better sealing! (I printed 1 part with PA-CF and a TPU lid modified with this method)</i></p><p>&nbsp;</p><p>&nbsp;</p><p><i>Update 05.05.2022&nbsp;</i></p><p><i>→ Added Smaller Versions to fit a 18350 Batterie (Scale this model up a little bit (only Y-Axis) for matches ,-) )&nbsp;</i></p><p><i>→ Added a cutout for an O- InRing in the OutRing version to secure a good pressure on the outer O-Ring (Makes sense, right? :D)</i></p><p><i>→ Added a few layers of material in the cap if you want to try out the burning Trick.</i></p><p>&nbsp;</p><p><i>Update 15.06.2022</i></p><p><i>Added <strong>Holder </strong>for the standard Container.</i></p><p><i>Big: Fits all normal versions fine and grabs them tight.</i></p><p><i>Small: Fits all normal versions and the small versions except EDC_Outring_Small.&nbsp;</i></p><p><i><strong>Print tipps</strong>:&nbsp;</i></p><ul><li><i>Print the holder with the seam on the backside. That will prevent twisting while using only one holder.</i></li><li>If you have problems sticking the parts together heat the left side (U-Grab) up with a fire carefully. Then connect the pieces together. However, this was not necessary for my prints.</li></ul><p><i>Update 28.09.2022</i></p><p>Added TPU O-Ring stl´s. Use with very soft TPU only!&nbsp;</p><p>&nbsp;</p><p><i>If you like my work, I would be very happy about a small tip :)</i></p><p>&nbsp;</p><p><a href="https://www.paypal.com/paypalme/MeisterEdel"><i>https://www.paypal.com/paypalme/MeisterEdel</i></a></p>
