Pinshape
I have inspired by the design from Thingiverse here. I modify the triangle shape to a round shape. It will increase the contact area with the bag which gets a better seal results. And add a little longer item for recent usage. Now they are 50 mm, 80 mm, 120 mm, and 160 mm long, respectively.
The seal result is very promising.
It is almost leak-free.
I think it’s better than the old version.
If you want to get a better seal result, choose the small printing height. I use 0.2 mm with PLA.Detail information
