Parametric OpenSCAD Round Container Jar with a screw lid

Updated 16 Nov 2024 - inlude chamfer option

Updated 27 Nov 2024 - Smooth Sides option

I was looking for a parametric round container with a screw lid. Couldn't find anything on Printables but found an excellent design over at Thingiverse.
 

It was part English and part German so I did some English to German translation .

Using OpenSCAD 

• download OpenSCAD  https://openscad.org/downloads.html Note: scroll down and download a developer snapshot, the 2021 version will not work.

• open the  .scad file  

• make any changes you need

• Use F5 to preview the model or via the menu Design/Preview 

• Once you are happy with the model use F6 to Render the model or via the menu Design/Render 

• Use F7 to Export the STL or via the menu File/Export/STL

You can find shortcuts for preview, render and STL on the menu bar 

Customising the Model

1. Set the width e.g. Inner_Width_Base = 120;

2. Set the height e.g. Inner_Height_Base = 32;

3. Set a Chamfer e.g. chamfer_lid = 3; chamfer_base = 3;

4. Choose if you want Smooth sides e.g. smooth_sides = 0; // [0:no, 1:yes]

There's a bunch of other options to tweak the thread etc. So far I have not needed to change those.

Errors 

You need a recent version of OopenSCAD the defailt 2021 version doesn't work, scroll down the downloads page and get a recent developer snapshot version.

If you choose to create both the cap and body with this option:

part_to_print = 0; // [0:all, 1:Base, 2:Lid]

You may get this message. You can ignore it.
