Inhaler Cap Replacement

prusaprinters

<p>I only have occasional asthma attacks, so my inhaler lasts a long time.</p><p>In fact, it lasts long enough that the cap becomes loose after a while and comes off in my pocket.</p><p>So I printed a slightly smaller / tighter cap.</p><p>In the pictures, the orange cap is the one that came with the inhaler and the "natural" one is the replacement I made.</p><p>Update June 2019: After a while, the replacement cap became loose as well. I reprinted, double the scale in the z-direction only, and that cap seems much tighter than the first. Don't have time to upload a new version right now, but modification should be easy enough with every slicer software which which I am familiar.</p><h3>&nbsp;</h3><h3>Print Settings</h3><p><strong>Rafts:</strong> No</p><p><strong>Supports:</strong> No</p><p><strong>Notes:</strong></p><p>While this isn't an item to be used with food, the cap does cover something that goes into my mouth on a semi-regular basis, so there may be a long term health issue with bacteria growing in the crevices of the cap.</p><p>To mitigate this concern, I dry my inhaler (usually on my shirt) before replacing the cap. But I'm still planning to keep an eye on the cap for any evidence of unwanted bacterial growth.</p><p>If the cap is too tight or too loose due to either variation in printer performance or the dimension of your inhaler, it should be a simple matter to scale the cap with your slicing software.</p><h3>How I Designed This</h3><p>This was simply a matter of measuring with the original cap with calipers, transferring that data to Fusion 360 and then printing it out. Then I iterated over the inner radius of the cap until I was satisfied with the fit.</p>
