123cm Block +

Like a typical 123 Block, only instead of being 1x2x3 inches; it's 1x2x3 centimeters. They have 5mm holes to screw together into different custom jigs. Very useful in RC at this size. Depending on your print settings and the object in question, can also be used to protect fine surfaces from light clamping loads.

EDIT: More sizes~
