Formaldehyde Molecule
Description
This is the 3d model to print of a formaldehyde molecule. Print 2 halves of oxygen and carbon. 4 halves of hydrogen. Try different colors for each atom. Glue them all and you'll have the full model. The chemical formula of formaldehyde is CH2O: it has one carbon (C) atom, two hydrogen (H) atoms and one oxygen (O) atom I've created this designed to my son's chemichal project and decided to share with you. The carbon atom is 40mm diameter, the oxygen atom is 38mm diameter and hydrogen atoms are 34mm diameter. I've printed all of them using 0.16mm layer height, 3 top/bottom solid layers, 3 outline perimeters and infill of 0%. No support at all.
