About this 3D model

A set of bars to teach fractions I made for my Wifes school. Set is 1 (Whole), 1/2, 1/3 1/4, 1/5 1/6 1/8 1/10. Bars are 15mm High, 2mm Thick (+1mm for the text) and between 15 and 150mm long. I printed at 0.2 Layeres with 3 Solid top and bottom & 3 perimeters. A full set weights approximatly 50g and took me 3 1/2 hours to print.
