Lamp for ikea kapplake LED spot

I made this mini lamp for the small and cheap IKEA spot called KAPPLAKE.
The button toggles the light on/off by clicking the bottom of the spot.
The base extends below the button because otherwise such a tiny lamp would just flip over if pressed.

Info:

Shade height: 70mm
Total height shade + base: 81mm
Base 50 x 50mm
 

Print recommendation:

• Important: Classic wall generator is recommended for the shade. Arachne result in messy seams everywhere.

I printed it in PLA using 10% Infill, 2 walls, 0.4mm nozzle, 0.2mm layer height.

Attached step files of everything, including a version of the shade without any chamfer or pattern.
