Customizable Ornament (Inspired by Blown Glass)

thingiverse

I wanted to 3D-print some Christmas ornaments in the style of the blown-glass ones my parents had. Ryan A. Colyer's [Plot Function library](https://www.thingiverse.com/thing:2391851 "thing:2391851") made it possible! Code update Dec 13 '17: I have added an automatic calculation to fit the shape to the cap, but you can still adjust it yourself. Parameters to smooth ripples near the tip and/or cap can improve prinatbility. Several parameters have been moved to an "advanced-tweaks" section so you don't need to worry about them unless you want. Also, I reorganized the code and decomposed it into multiple functions to make it easier to understand if you want to edit it yourself. (I'll try to come up with a better picture; we don't have a tree yet this year and while we bought a wreath, haven't hung even that so I just looped it over the end of the railing :-) #### If Customizer is not working Sometimes the customizer app gets overloaded and isn't working, but you can tweak the code yourself! All you need from here is to download the ornaments2.scad file. From http://www.openscad.org/ download, install, and run OpenSCAD. Open the ornaments2.scad file, change any settings you wish, then preview, render, and export. Pretty simple, really. If you can use a word processor, you can do this! I put a labeled screen capture into the images showing you what to do. #### Customizer Caution! *It is possible to set parameters that will produce shapes that are **impossible to print.** * Please review the explanation of the settings (see below) before you begin, especially if you are new to 3D printing and can't tell just by looking whether a shape is likely to print well. (I understand that leaving parameters is contrary to Thingiverse's best practices; if people find it too problematic, I would be willing to fork a safer version.)
