About this 3D model

This is my second fidget spinner project for Myminifactory and TinkerCAD challenge. I change my first ballisong knife fidget spinner by making it much smaller and using NO metal bearing this time! Because of it's size! Bearing is too big! So i desined a 3d printable bearing that works perfectly! This project is realy easy to print! No supports needed! And the assembly is realy fast and easy! Just look at photos! You can glue knife pins together to make all fixed well, but it all works fine with no glue! Have fun with this balispinner little brother! And if you have some ideas to improve it just let me know! This object was made in Tinkercad. https://www.tinkercad.com/things/hg9VVpx7cLc
