Description

A co-worker lost the cap to the coolant reservoir on his 2010 Dodge Ram 3500 6.7L Diesel truck. He could not find the CORRECT part anywhere- all of the caps sold online were the same part number- and all too small for his overflow tank's opening. The washer fluid tank used the same exact lid, so he brought that to me to copy. I managed to get a good fit on the 2nd try.

I suggest printing in Nylon. I used Taulman Nylon 645. It's flexible enough to fold in half as it needs to, heat resistant, and tough.

June 2019 update: 12 months on, my co-worker says the hinge of this cap is still intact, the cap still fits snugly after several openings & closings, and the entire piece has withstood the Florida heat & humidity thus far.

Pricing assumptions and exclusions

USD: ($6 setup + $3 finishing + filament weight × assumed spool cost × 1.25 waste allowance + print hours × $2.50 × material time factor) ÷ 0.65. Rounded up to the next $0.50.

Assumed spool costs per kg: PLA $25, PETG $30, ASA $40, ABS $30, TPU $45, Nylon $65, PA-CF $95. Time factors: PLA/PETG 1.0, ASA/ABS 1.2, TPU 1.6, Nylon 1.4, PA-CF 1.5. These are proposed shop rates, not measured production costs.

Design work, test fitting, hardware, shipping and tax are additional where needed. Multi-file sets may need several prints. Use actual sliced weight and time when available. Final pricing is confirmed in writing.
