About this 3D model

Finally I could have my own wrist reset for my keychron. The dimension is 360 x 68 x 22 mm. and it is foldable to fit into your bag. No support needed. The diameter of the axis insert has already been adjusted, and due to the elephant effect, it might be tight to insert into the hole. I suggest to apply some lubricant into the holes and use the hammer, after the insert is completely installed, the rotation is smooth.
