班級教室用籤筒

作品介紹：
這是一款專為國中小學教室設計的「班級共用籤筒」，放置於講台上，提供任課老師隨時取用。使用12.5公分長的冰棒棍作為籤條，每支籤標註座號，便於點名、抽問或小組活動。抽籤方式簡便，只需輕晃容器，即可從蓋面小孔自然滑出一支，兼具趣味性與教學實用性。

設計特點：
本作品採用螺旋蓋設計，密合好收納，蓋面小孔方便單支籤條自然抽出。內部空間經精確設計，建議最多放置35支冰棒棍，以避免壅擠、提升抽籤順暢度。整體造型簡潔，結構穩固，無需支撐即可列印，後續清潔也相當容易。

尺寸與相容性：
本籤筒相容標準冰棒棍尺寸（長12.5公分、寬1公分、厚2毫米），可直接購自文具店或手作材料行。可依使用需求加大外觀高度，但原始設計建議容量為35支以下。

列印建議：
列印層高建議0.2mm，使用PLA或PETG皆可，若考量耐用性與濕氣，建議選用PETG。整體設計無支撐需求，直接列印即可。

應用情境：
供全班教師共用之教具，可用於隨機點名、討論分組、課堂提問順序安排等。籤條內容簡單標註座號即可，亦可搭配顏色辨識學生組別或進階任務設計。

Shared Classroom Stick Picker

Project Description:
This is a shared stick-draw container designed for classroom use. It is intended to be placed on the teacher's desk for use by all subject teachers throughout the day. Each stick (length 12.5 cm) is labeled with a student seat number, making it easy to randomly select students for answering, grouping, or activities. A simple shake allows one stick to slide out through the lid's slot — functional, fair, and engaging.

Design Features:
The design features a threaded screw cap for easy opening and secure storage. The narrow slot on the lid is sized to allow only one stick to exit naturally. The inner volume is precisely calculated to hold up to 35 sticks without overcrowding, ensuring smooth draw operations. The cylindrical body is clean, support-free for printing, and easy to maintain.

Size Compatibility:
Fits standard craft sticks measuring 12.5 cm long, 1 cm wide, and 2 mm thick. The model is optimized for a maximum of 35 sticks; overfilling may affect drawing function.

Printing Recommendations:
Use 0.2 mm layer height. Materials: PLA or PETG. PETG is recommended for better durability and moisture resistance. Model is fully support-free and ready for direct print.

Classroom Applications:
This is a practical tool for all teachers in a classroom setting. Use it for random seat number calls, group task assignments, or answering sequences. Simple seat number labeling is sufficient; color coding or tags may be added for advanced uses.
