Mini Grenade
Print Profile(2)
Description
The design originated from my personal needs
I have very few keys now, just a car key and a house key
I wanted an interesting, combinable keychain that could separate two keys at any time and then reassemble them, but I couldn't find one
Some time ago, I made a long version, about twice the current size, which has been very stable for several months
Recently, I modified it into this half-length version
It feels a bit like pulling the pin on a grenade, so I named it "Little Grenade", it can also be called a mother-child buckle, couple buckle, or something similar
Other possible combinations
Little Boy + Little Japan
Green Frog + Taiwan
YJ-21 + Ford aircraft carrier
XX+YY
Anyway, any related items can be connected with this thing
Smooth pulling feel once stable
The layer lines provide a detailed friction sensation. Sometimes I just pull it back and forth for no reason.
Printing Notes
The build plate must be clean, although a skirt is added, there is still a risk of tipping over
For the smallest part, PETG is recommended. PLA might break because it's too small
Different materials have different sinkage rates. The current default scaling is 100% for the outer cage and 99% for the fork rod. If it's too loose or too tight, adjust these two shrinkage values yourself.
I personally recommend a tighter fit; it will become smoother with prolonged use
