The Alfawise U20 is a big printer and does not fit the Ikea Lack table. I needed a small footprint similar to my Anet A8 so the box here consists of an enclosure of the mother board inside the U20 black box, plus 2 TL smoothers, for the X and Y axis.
the LCD is in an enclosure, fixed to the main bord with double sided tape, strong enough for this purpose.
The box is way smaller than the original one. It does not heat inside so a fan is not really required.
The Power Supply is outside this box, on a vertical stand.
EDIT: I have uploaded the version with the fan inside the box. A 40x40x10 24V connected directly to the mother board on J14.
There are 2 versions of the top in the provided files, one with the hole for the fan, the other one without.
