This is holder for AC adapter of PC.
Size is specific for Panasonic model.
My AC adapter size are below.
W102.1mm x D 43.3mm x H 28.3mm

Adapter should insert from front side and it will be placed by front edge and side edge.

QIDI TECH 1

0.2mm

I had used ABS for it.
Raft may cause good result

My wife gave me a lot of claim when this AC adapter comes in with new Laptop.
Because AC adapter jack has moved to opposite side and she felt it as messy.
So cabling problem should be solved with AC adapter placement at below table and wires are thorough under table side as hanging.
