hello i need help creating a Twist Snap Mechanism in Fusion 360 for something im working on, ic ant figure out how to make it, im super new to this and dont have much experience with these things. all i need is a cap that wheny ou twist itll open twists back itll close, but had to be air water tight, cant really figure it out, hoping someone knows what theyre doing

Bruh, patience, that inactivity happens to all.
Do you have a sketch or something? Very hard to understand from your description
harsh wing
im arguing with the bot sorry
if anything that benchybot is impatient 😤
yeah i think i have an idea of how itll work but too new to model it myself its this, but i want the pins here are for screws, id rather them be snap on kinda thing so i dont have to use screws, just print separately then it just snaps together, also i wanted the half leaf thats considered half of the lid or whatever you wanna call it, id like it to be able to interlap, like 1 us a U shape and the other is a tad smaller and just interlaps but still works perfectly, so it genuinely closes and doesnt have that micro gap if you wanna call it that
may have to adjust the stop for the one side since itll go in a tad farther itll need to retract a tad farther too
im just not cool enough to do it myself i guess, its stressin me out dawg
cunning cosmos
Erm, one problem at a time.
harsh wing
yes sir
cunning cosmos
To model some pins for snapping in would be easy, although the pins themselve would be pretty weak. Layer adhesion is always weaker than layer itself. i'd suggest to use heat insert and a screw instead, if you need it to be sturdy
and you want that section to be air tight?
harsh wing
ik the problem im having is i cant use screws on it, i need it to be set together with no screws, i wanna be able to snap it together and it kinda just stay that way even if i cant take it apart, is there any way to get around that just using petg. also the whole thing is meant to twist and it opens the middle, the 2 half circle leaf looking pieces come together fine but i want it so nothing can fall out of it, since just like that itll always have a microgap, so what i was thinking is hollowing one side out a tad then the other half will interlap and go inside it just a little so it has more of a seal
harsh wing
yeah i just watched the attached video and it looks a little weak, im sure theres ways to make it a little stronger
i dont have experience with snap fits so idk how well any of these work, i also dont know how well petg holds up with all that'
cunning cosmos
Petg is pretty much elastic but after that it just snaps. Last one is pretty weak imo.
harsh wing
what do you recommend, would pla just be better all together
cunning cosmos
I'd say print the pins as separate parts and snap in in both parts, The pins will be stronger that way
harsh wing
im using fusion rn, is there a better one out there i could use, this ones just awkward
cunning cosmos
Fusion? Fusion is pretty easy compared to others.
For the lids closing:
add something like this to one side (sketch a shape and then sweep along the edge of a body)
move the lids togeteher, boolen cut out, offset faces a bit, like 0.1mm 0.05mm to have some clearance
harsh wing
so just a thin layer that overlaps the other? is that what that is?
cunning cosmos
pretty much
just make the sides a bit slanted to make it easier to move apart. This is like 5°
Good idea comes too late, as always: you can make it like 30° slanted to print it out without supports
harsh wing
make this side 30° slanted down and the other side slanted up?
harsh wing
ohhhhhh im tracking now
im still trying to figure out how to fill a hole so itll take me a second
cunning cosmos

Are you trying to edit stl directly?
harsh wing
yeah, i filled a hole, trying to refine it to get rid of lines, but my combo view is broken, cant toggle it in my panels
cunning cosmos
harsh wing
apparently even if the history isnt there you can still just delete the hole
harsh wing
im baffled how you did the
cunning cosmos
im baffled how you did the
Look up sweep function in fusion
harsh wing
i think i gotta scratch that idea, its on the back burner rn, what im trying to do is make a lid thats an inch to an inch and a half wide, and after scaling that contraption to what size i needed the opening, it scales to 3 inches wide and thats way too big
harsh wing
gotta figure out how to put a cap on this on the top, the bottom has a screw on cap, the top i want a lid that is powder/air tight, and is able to open without taking the cap off, kinda what you were helping me work on earlier but way less smaller, and no screws or metal
ik im complicated
idc what it is as long as it opens with a flap or something but doesnt come off, and is small enough to put the whole thing in my pocket
low key if you get something thrown together to work like that, ill throw you some money on cash app or something
manic ice
idc what it is as long as it opens with a flap or something but doesnt come off,...
why wont the same screw work on the top?
harsh wing
Because I want a flap or something that you dont have to take off. Like a quick release cap I dont want it to leave the bottle if that makes sense

what about stuff like this?
and why no metal? 
mellow walrusBOT
harsh wing
and why no metal? <:thinkies:961512478683050034>
More contraction, more material cost. All that good stuff
Plus cant take it through a metal detector lol
