Desktop extension, load-bearing capacity of approximately 3kg

Desktop extension plate, extension area 100*250mm, thickness 3mm, inner reinforcement supports 5kg, outer supports 2.5kg, the support of the reinforcing beam can be left unremoved to further enhance strength. The desktop is fixed with nano glue or similar adhesive. Due to the relatively dispersed force, the bonding strength does not need to be very high. The extension plate is 3mm thick, and the desktop bonding area is 50*30*2.5mm in the middle, 20*30*2.5mm, and the side bonding area is 50*20*2.5mm / 20*20*2.5mm.
