In all other cases I approximated to match the pictures in Dana's book. Please note that I do not have an original set to compare, so there might be small differences. Also the scaling is arbitrary and probably totally different.</p><p>There's a labelled (by catalogue number) and unlabelled version. I also include the OpenScad file I used for embossing, in case somebody wants to adjust the labels.</p><p>Changes I made to correct apparent errors in the catalogue (to match Dana's book):</p><p>No. 54: added {1 -1 1} to match picture</p><p>Big Thanks to Prof. Gervais Chapuis for making me aware of this set's existence and sending me his catalogue!</p><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>BIQU B1</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>Yes</p><p><strong>Resolution:&nbsp;</strong></p><p>0.2mm</p><p><strong>Infill:</strong></p><p>10%</p><p><strong>Filament:</strong></p><p>3DJake PLA</p><p>glitter gold</p><p><br>&nbsp;</p><p><strong>Notes:</strong></p><p>&nbsp;</p><p>Some of the models require supports.
