coffee carafe replacement top cap - distiller enhancement by freNRG

Last crawled date: 3 years ago

so , .. i left the pot of water boiling too long, flame was low good thing , but all the water was gone and teh thing heated up to the point that the top melted (as seen in photo)-- to the rescue is 3d printing (i seriously doubt i could buy that plastic part replacement and then the wait for shipping !!)
I was able to very carefully break and manuever the melted plastic ring that i thought was stuck at the top.. it did take a lot of prying ! (with plastic lever) ..
i realized, my distillation set sucks with only 500 ml boiler .. now with this I can mulitply by 4 times and have a 2 LITER boiler !!! ... (this was more the motivation to make than just for boiling water for tea/coffee()
last picture, using a recycled (golf ball) as a stopper in the center, water is boiling and steam is protruding up (though picture detail doesn't seem to capture this) - i didnt think pla would hold up, ball is abs .
Distil v3 is the latest (17Dec15) -all the height is not needed, i tried tquickly reduce the amount of material to mostly what is functional, i did find that after about 5 min of boiling, the PLA becomes soft and the parts 'work themselves into the groove' ( it gets better with use) -- pla becomes soft at 60c so at 100c this is expected to happen --- on the v2 test a very low infil (about 2 or 3 ) was used -- about 30 grams at 3%, i suggest 5 or 10 infill so it doesnt collapse with longer boil times -- i hate to use ABS because th is not organic, so better to use more infil and stick with the pla, and not have the temps stay too high (keep flame low so pla does not melt too much) -- perhaps a thicker wall as well -- the real test will be 1 hr boil time to see if it holds up ..
