Pencil-Shaped Pencil Box

[2025-0918 Update]:

Fixed a hidden bug where the top cover was prone to deformation under heavy pressure, causing stress to transfer to the rotating shaft, which could easily break This has now been completely fixed by adding a rotating shaft guard After actual printing tests, it runs perfectly Additionally, the overall length has been reduced by 4mm, slightly reducing printing time and the overall length of the pencil box

Design notes:

        As my child entered third grade, the third pencil box was created This time, a classic pencil shape was used for the pencil box's appearance In my opinion, the most classic pencil shape is this one:

However, the classic prototype would result in a hexagonal prism, which is not suitable for actual school use scenarios So I spent some time redesigning the angle of the pen tip and the curve of the "cut tip" to restore the classic pencil's aesthetic elements as much as possible while rationally balancing the slim form of a practical pencil box After extensive printing and detailed refinement and optimization, this time I directly removed the use of magnets and switched to Print in Place snap fasteners, saving a lot of trouble with magnet installation However, printing this pencil box will be more time-consuming, and one part will require super glue The reason is for the final aesthetic quality of the print Fortunately, I have already tested it If everyone uses the same Bambu Lab official filament, you can reproduce the print

        If you need to engrave text on the surface of the pencil box before printing, I have set up a custom text area, which can be customized by double-clicking within the slicing software Of course, a non-engraved version is also available for selection

About printing instructions:

1. Because the model is designed for optimal final print quality, the panels are printed vertically It is highly recommended to apply glue to the PEI plate before printing

2. If changing filament, be sure to reduce the maximum volumetric speed of the filament to ≤20mm³/s This can effectively suppress panel ghosting in the vertical direction

3. To save time, print the black pen tip separately

4. Cleaning the printer's build plate is the foundation for stable printing of any model It is highly recommended to apply glue to ensure a successful first print

Additionally, a note on the rotating shaft of the pencil box: the rotating shaft of the pencil box is the filament itself It automatically latches into the shaft hole using elastic principles For details, it is recommended to watch the video Finally, I wish everyone a good time!
