About this 3D model

I lost one key when cleaning my keyboard and could not find any replacement to buy so I decided to design from scratch. First design was perfect but I had problems fiting the cross to the board because of the supports and acuracy. Finally my design fits 100%. You don´t need to use supports. Once print is finished you must brake the end of the inside cilinder. It is designed to brake easilly so the cross apears and you can fit the key into de board
