Vase Generator Parametric Design

This Fusion 360 modell allows you to model the vase you want, by changing it's parameters. I always found it difficult to find a vase with the size i am looking for. Sure you can scale the model of an stl, but height and  diameter change the same way. 

Instructions:

To change the parameters of the model go to change→ edit parameters ( as shown in the 2nd and 3rd picture). The design is based on 2 different splines (see last picture). A spline is a kind of curve which follows 3 or more points. You can change the shape individually by changing the parameters Spline_1or2_XorZ. The value is in percent of the height(Z-value)/radius(X-value) and changes the position of the splines middle point. The “diff_seg_radius” determines the difference of the opening radius of the splines (end point). The size of one segment can be changed by changing “Segment_size”, which is the size in degrees. 360 needs to be dividable by the value, to make it work. If you change this parameter you may need to combine the generated bodys manually, because fusion can't combine bodys after generating a patternfeature (this might not be the right word for fusion; this is the term used in Siemens NX). To combine simply double click the last symbol in the creation history at the bottom left (second last picture) and click all the body you want to combine. If you know how to improve this please let me know. You probably need to play around with the parametrs a bit to understand how the parameters change the shape. You can also fine tune the spline individually when double clicking on the sketches.

Some Tips:

Try to keep the difference of the two splines low, to save material and print time. It's best to use a section plane to analyze. Make sure the overhang isn't that steep otherwise you may run into problems, because the printed part get's pushed down by the nozzle and bends down.

if your new to 3d printing, you need to print this in vase mode or spiralize outer contours, which is the name in Cura.

I hope you enjoy this. You can share your generated model as your design if you want, but please don't share the Fusion file. I would be happy if you share your creations as a make, to see what you have created :)
