If you read Rugged Box Silicone Gasket Seal (Part I) you read about how I used CHANGTIKEJI Silicone Mold “Super Elastic Liquid Silicone” to make a gasket (seal) for these 3D printed rugged boxes.
But I wasn’t completely happy with the results…
I sort of wish there was a way to “glue” it into place, but you can’t exactly glue silicone, because it doesn’t really stick to anything! I do have an idea for that…
The one thing I don’t like with this one is that it easily falls out. If this is a box you open a lot you’ll probably get annoyed with it falling out on occasion.
So I wanted to try a few thing to solve those annoying issues…

Someone on Mastodon had the idea to pour the silicone directly into the groove of the box. (I can’t seem to find that reply right now!) I thought I should try that. It was not easy. It was messy. And I had to do it twice. The first time I leveled off the silicone with a wooden popsicle stick. Once it dried it sort of sunk down a bit… I did it again, this time dripping (drizzling?) it into the groove just a little at a time with a popsicle stick. That gave me a lot more control versus pouring way too much. (Luckily it peels off when dry.)
One other issue is that once dry the lid would not close! I ended up shaving down the lock just a bit and using some good pressure to close it. Again, I may need to mess around with the TSealHeight parameter to get things just right.

Finally, I tested it for water-tightness by doing to paper towel submersion test and… it failed. So not water-tight, and not a good fit.
Also, while the idea to “glue it in place” by pouring the silicone directly in was a good one… it just came out very easily. Maybe because it was so thin.
Anyway, this was a good test! I have another test that I just finished, so keep an eye out for the next post!
