Vitamin C, E and OPC - OpenSCAD generated from chemical SDF file

pinshape

Molecule structure STL files are generated by OpenSCAD, a program that originates from "sdf2scad.perl" Perl script derived from NCBI PubChem database's 3D SDF format files. For generating scripts and notes, refer to http://www.thingiverse.com/thing:689652 (Water and Ethanol). Wishing you excellent health for your 3D printer! A combination of Vitamin C (L-ascorbic acid, C6H8O6), Vitamin E (alpha-tocopherol, C29H50O2), and a unique OPC (proanthocyanidin A2, C30H24O12) is used. The 3D data construction (SDF file) comes from the PubChem Project at https://pubchem.ncbi.nlm.nih.gov/. Instructions can be found at http://www.thingiverse.com/thing:689652 (Water and Ethanol). Microsoft Model Repair Service was utilized for generating STL files using OpenSCAD, accessible via https://modelrepair.azurewebsites.net/, requiring an MS account. The Vitamin E and OPC molecules are the largest in my chemical work series; some printers may find it challenging to build them. With my Da Vinci 2.0 printer, I scaled the model to x8, set a pitch of 0.2mm, used low speed, and single extruder (with white filament) for optimal results, but unfortunately, 4 hydrogen atoms were lost in the process. To rectify this issue, I removed excess hydrogen from unused caffeine and bonded it with acetone, effectively fixing the problem through chemical means.
