Grayl Ultrapress screw cap fixation

prusaprinters

<p>This is an easy print for adding an eyelet hole to the Grayl Ultrapress. I love my Ultrapress but other than the Geopress, the screw cap has no fixation to the bottle. I use it often when standing in the rivers while Flyfishing and I´m always aware of losing the screw cap forever in the waters.</p><p>The original screw cap is glued into the printed adapter cap. Before you glue it, place the eyelet into the adapter and make sure it moves/rotates freely. When glueing, make sure that you don´t put glue onto the eyelet bottom. Otherwise it won´t be able to rotate because it´s glued together with the original screw cap top.</p><p>I printed it in PLA with 0.2mm layerheight. Of course it works with PETG and other materials as well. I used a base support as well to print the outide chamfer properly.</p><p>&nbsp;</p><p>You may be interested in mhparsons Grayl Ultrapress Holder</p><p><a href="https://www.printables.com/model/210773-grayl-water-purifier-holder">https://www.printables.com/model/210773-grayl-water-purifier-holder</a></p>
