Update March 29th, 2020
I've updated the design so it can withstand rigorous use such as wearing one and exercise (in my case, kickboxing). The old versions are still there if you need a legacy design for some reason. The new batch has files start with [vial]
SAR-COV-2, aka. Covid-19 aka. Wuhan Coronavirus aka That virus going pandemic right now (end of 2019 to early 2020 and likely beyond), is coming. It's better to be prepared.
Washing hands is the best way to prevent the spread of the disease. But what if you cannot do that? What if a lot of people are using the sink and you just cannot go without. It's time to use a hand sanitizer, but that thing is bulky to carry around.
With this print, you can put a dose of disinfectant and wear it around.
I make 3 varieties of the vial. First, which I use daily, a glasses-frame mount vial. Very unintrusive. Printed with the same color of the glasses frame. Most people in my office don't even notice the item. The second is a cloth clip style. The third has a hole for a rope or necklace to run through and wear around your neck, wrist, at your convenience.
You will also need to print a cap. Using the same setting. Recommend to be printed with the vial of your choice.
For the model I am using, please check the printing tips. This one is tested with 99% Isopropyl alcohol for 24 hours and it holds without the thing evaporating, and it seems to maintain its effectiveness under the test duration (3 specimens, 24h containment test)
For the glasses-frame mount model, put it on with the cap away from your eyes. It has never leaked on me but it seems like a good idea.
Again, it is important to note that this is to be used in a bind. Wash your hands. When you cannot, this may help.
PS: This is pretty much a work in progress. There may be changes or improvements later.
Addition (Mar 5th, 2020): I've discovered that this print cannot withstand rigorous activity. After 5 uses, the screw cap becomes a bit loosed. It holds just fine until it was shaken rigorously. I wore it in my kickboxing training and after kick and getting kicked for a while, the cap broke free. A new, more durable design is on the way (testing). Will upload once I make sure it can withstand at least a few more kicks.
