Computer Mysteries
All entries must be pre-entered on a General Entry Form at the York County Extension Office by the first Friday of July. All Exhibits will be judged on Wednesday of fair week in Ag Hall. Entries must receive a Purple ribbon at county fair and be selected to advance to State Fair.
This category gives 4‑H members a chance to display their knowledge of computers. Through participation in this category 4‑H'ers will develop presentations that show judges their knowledge in the different aspects of computer science. Involvement in STEM Computers gives participants a first-hand experience in modern technology. For help getting started with this project contact your county 4‑H extension office.

H860007 - 3D Printing (SF1050) - 3D printing uses plastic or other materials to build a three-dimensional (3D) object for a digital design (including 3D Pen Creation). 4‑H may use original designs or someone else’s they have re-designed in a unique way. Exhibits will be judged based on the motivation and/or problem identified. For example, 3D objects printed as part of the design process for robot or other engineering project. Must include design notebook that addresses the following questions.
- What was the motivation for your design or the problem you were solving with your design? i.e. Is your item a functional or decorative piece?
- Please include a picture of original design, citation of designer/website or if design is completely original (you created it using CAD software), then state that it’s original. If item was not completely original, indicate what you did to the original design to modify it to better meet the design problem stated in #1 above. Its design was modified multiple times, please indicate what change was made with each modification, and what prompted the need for the change. I printed it and the design was too fragile, so I resliced the print to make thicker external walls, or to have a denser infill.
- Define your process for designing/printing. What software and/or hardware was used (indicate type of 3D printer or if item was created with 3D pen)?
- What materials were selected for your project?
- If your final design has any moving parts, define how you determined appropriate allowance in your design.
- Identify any changes that you would make to improve your design.
H860008 – Maker Space/Digital Fabrication (SF1050) - This project is a computer generated projected created using a laser cutter, vinyl cutter, heat press or CNC router.

1. What motivated you to create this project
2. Software and equipment used
3. Directions on how to create the project
4. Prototype of plans
5. Cost of creating project
6. Iterations or modifications made to original plans
7. Changes you would make if you remade the project
Team Entry Options: To qualify for entry at the Nebraska State Fair team materials entered in H860008 – Maker Space/Digital Fabrication must clearly be the work of a team instead of an individual and must have at least 50% of all team members enrolled in 4‑H.
