Customized Pen Holder (Fast Printing)

The effect presented by this parametric model is very simple.

However, the difficulty in creating this project far exceeded my imagination. The code is more complex than other parametric models, at least for me, for the following reasons:

1. Letters like "i", "j", etc., easily create isolated islands, so I optimized the code for all letters individually;

2. The first and last letters are prone to overhangs due to internal circular and hexagonal cutouts, so each was optimized individually to avoid print supports;

3. Some letters tend to separate from adjacent letters, such as lowercase "L", requiring independent spacing adjustments based on their position;

4. Combinations of Chinese characters with numbers, English letters with numbers, and various symbols often lead to many unexpected issues, all of which need to be individually checked and resolved;

5. Adaptive chamfers were added to the top and base, which cannot be solved by simple cutting or Boolean operations.
