3D model description

Original files from the video as seen on TikTok!
To connect the blade to the housing I used an M3x16 screw and a nut with pin set V1. You could also superglue it in with pin set V2 if you don't have any bolts lying around.

I used an M3x20 screw to attach the shell to the main body.

Gravity knife blades V2 and V3 have slits cut in them to add a blade I believe but I wouldn't recommend it since it is supposed to be a fidget toy and it wouldn't be safe.

Print 1 copy of each category using supports

I use pin set V1, Gravity knife main V2, Gravity knife blade V1 and either Gravity knife shell V1 or V2 when I make mine which gives it a smooth opening and closing action perfect for fidgeting.

Print orientation:
Print in whichever way you want, I printed with the point of the blade pointing upwards and the shell with the outside flat side on the base and the main body facing upwards as well.
