Keyblade I made for last time 3D printer usages. I checked if someone else would have done this and couldn't find and when I was done with this I searched again and saw that burt45 had done 1.

Well at least it gave me some experience ^^.

it's 5,5cm long and 1,7cm in width.

( The measures might be off, I made this to be 5,5cm, but somehow when I was printing the 5.5cm was converted into 5.5mm.)

So I made 2 of these myself with 3D printer and figured that the object was still really tiny, and the printer didn't do a hole in the key.
So If you wanna do this you should try to do it around 8cm x 2,4 if you want the hole too.
