This is a Cable Entry for USB Cables w/ 4mm Diameter.
The Diameter of the Cylinder is 19mm, so it should fit easy in a 20mm hole.
It is 5cm tall so it fits trough the Top of the Ikea Lack Table.
I printed it with the Bottom Side down and used Support, so the curved Edge of the “Top” doesnt look ugly :)
Printed with 5% Triangle Infill.
