OPEN SOURCETire weights bring the finished goal close to the density of aluminum.
Please keep improvements open and derivative files free. Paid printing and assembly are welcome. Why keep it open?

Libraries and makerspaces can help you print files without buying a machine. Ask whether you submit a file or book a supervised session, whether training is required, and how long a job may run.
Confirm materials before buying anything. Many libraries supply filament and prohibit bringing your own; PLA-only machines cannot make a flexible TPU casing. Ask about PETG/TPU, fees per gram, queue times and collection.
Austin: one free monthly print for eligible residents ↗
Salt Lake County: supplied PLA, 6¢/g and a request queue ↗
CLUB COST CALCULATOR
playunderwaterhockey recommends the base Bambu Lab P1S . The base model is more than enough for gloves, sticks, and mouthguards.
Sticks: Print flat in the orientation recommended by the model. Use the maximum practical wall/perimeter count, then 100% infill when the design and final weight allow.
Goals: The example makes two weighted 2 m goals with eight sections each. At $13/kg, PETG is about $78 per goal, wheel weights add about $80, and printing takes about 4.5 days each. Four sections make 1 m; eight make 2 m; twelve make 3 m.
Mouthguards: Roughly 16–18 can fit on one plate. That reduces hands-on setup, but a failed plate can scrap the whole batch.
The goal comparison uses $2,500 for a pair—the midpoint of a typical $2,000–$3,000 metal-goal purchase. The weighted design aims for an overall density close to aluminum, while PETG avoids a fully metal goal that some pools may not permit. The calculator includes $10 in tire weights per section and a one-time $25 for goal magnets and glue when goals are selected. For whole-pack purchasing costs, use the weighted goal’s price calculator. The glove estimate adds $2.50 each for the base glove, glue, and small consumables. Sales tax defaults to a rough 8% allowance on both supplier purchases and DIY purchases, including the printer. Adjust it for your location. Shipping, electricity, labor, extra assembly supplies, and failed prints are excluded.
