party-hat-generator 🥳

Party hat generator for 3D-printing. Not suitable for children due to possible sharp edges and possible printing problems like delamination.

Print using vase -- or spiral mode -- for best results. See slicing hints when exporting.

Note: Text cutting and union + filleting is a little bit buggy, maybe used wrong, so all words will not work. Font size below 20 will increase failure rate. A possible quick-fix is to increase the model size 100% or more, and scale back before export or in the slicer. This is not implemented.

Installation

Recommended way (conda)

Tested with Python 3.11.

1. Clone this repository.
2. Install miniforge (macos: brew install miniforge)
3. Create a virtual environment for qadquery 2 and install a specific version (tested with party hat generator):

conda create -n cq22
conda activate cq22
conda install -c conda-forge cadquery=2.2.0 occt=7.7.0

4. For using emojis, download the Google Noto Emoji font here: https://fonts.google.com/noto/specimen/Noto+Emoji and put the font in a new folder called Noto_Emoji next to main.py. Like this: "Noto_Emoji/NotoEmoji-VariableFont_wght.ttf".

Deprecated (pip)

Using pip, not recommended as cadquery 2 series plays better with conda. Tested with Python 3.9.

1. Clone this repository.
2. Create a virtual environment.
3. Install python dependencies using pip install -r requirements.txt
4. For using emojis, download the Google Noto Emoji font here: https://fonts.google.com/noto/specimen/Noto+Emoji and put the font in a new folder called Noto_Emoji next to main.py. Like this: "Noto_Emoji/NotoEmoji-VariableFont_wght.ttf".

Step 3 will install a specific cadquery version, as this project is dependent on 3mf export format support. You could need to upgrade your slicer to use the produced files.

Making a hat

Edit list of names, icons and/or font size in main.py. Run main.py from the conda (or pip) virtual environment, and hopefully get a 3mf file ready for slicing using Cura or another 3D printer software.

Material consumption: Around 12 grams of PLA filament for one hat (95 mm diameter).
