Abstract
The purpose of this project was to create a portable, collapsible, disc golf station primarily from materials diverted from the waste stream. The project also must be reproducible so it can be integrated into the curriculum at Zane Middle School to further educate students on sustainability and the use of upcycled materials.
Problem statement and criteria
The objective of this project is to design a portable disc golf station from upcycled materials. The design of the station will be based upon Professional Disc Golf Regulations and criteria given by the client, Zane Middle School.
Description of final project
The Decked-Out Disc Catcher, fully diagrammed in Figure ?.? is the final design for a disc golf basket. The main components of the basket are a 55 Gallon HDPE drum, 3 skateboard decks, chain, and PVC pipe. It is PDGA regulation size, collapsible, and upcycled.
The Basket: The basket is designed to catch discs without damaging them. The top of the basket is made by cutting the bottom 4” off of a standard 55-Gallon HDPE drum. Every 6”, there is a hole drilled ½” above the cut, numbering 12 in total. These serve as the attachments for the s-hooks, which hold up the chain. The top of the basket is attached to 3’ of 2” schedule 40 PVC pipe via a 2” flange. The 12 chains are cut into 24” segments. The bottom of the chains connect to a 5” metal ring which hangs around the PVC pipe connecting the top to the bottom of the basket. The bottom of the basket is made from the top 8 inches of the HDPE drum. The bottom of the basket is attached to the PVC pipe with a 2” flange.
The Base: The base is designed to support the weight of the basket without falling or wobbling. Our base consists of 3 standard skateboard decks affixed to the bottom of the basket using hinges. The hinges are attached every 25½” of the circumference. This tripod design provides sturdy support, and also allows the skateboard decks to fold up against the bottom of the basket.
Costs
Design Time Input
The design costs for hours is the amount of time spent working on the project thus far. The total is 65 hours spent on the project. The most time was in section 2, the literature review and problem analysis.
Maintenance Costs
The only maintenance is possible repair costs. These repair costs will depend on the part that is broken. The price can be found in the previous table. The nature of the project is using up-cycled materials, so there will not need to be maintenance cost for most of the parts.

Testing Results
Testing the Decked-Out Disc Catcher showed that it was indeed a sturdy and reliable design. The design catches discs without damaging them and without the basket tipping over.
How to build
Discussion and next steps
After our research we concluded that plastics such as PVC and HDPE were the best option for the basket. Field use by large groups of middle schoolers of the disc golf target will show how long it can withstand the inclement weather of Eureka and any other design flaws.
