Description

A cap for sealant tubes. Section view shown for clarity.

I used to use a long screw. I tried the “condoms” - they don't work for me. This should work the same as the long screw, as it protudes into the sealant tube.

I added a profile to print at 45°, as this will make the needle stronger. Cut off the supports when done.

I’ve used a lot of silicon in my life. If it’s less then a month between uses, I find it’s much more effective to literally do nothing and leave a pig tail of silicon at the tip. You grab the pigtail and fresh silicon is behind it. or at most a .5cm cut I the tip will allow access to fresh silicon. Using a wide nail or similar - introduces a small amount of air into the silicon and causes more of it to go off. I’m sceptical that this would indeed cause much more silicon to go off, however strangely I’m keen to try it. Can anyone here confirm long term success before I waste any plastic? The needle part seems unnecessarily long by several orders of magnitude?

I have previously been using a long screw, which works for quite a while because when you remove it there is a passage through to the uncured sealant in the tube. The sealant cures from the open end, and driving a screw in doesn't appear to introduce any air. Hence the long needle, it penetrates the full length of the nozzle. I have used one for a couple of months and yesterday I was able to remove the cap and use it. I was a bit concerned because that cap was printed in PLA, that when twisting it off the needle might snap off, but it was fine. I can't make any guarantees on how long this will work, and it would depend on the type of sealant, but it will prolong the usability of the tubes as well as or better than a long screw.

Replying to @user_484565628 :

thanks for the reply. I might give it a go! I go through some sealants quickly. And others sit for longer periods. Many times sealant has gone off and it’s basically ruined the remaining tube. I endeavor to update my reply some time in the future, Thanks for the design :)
