Material Costs¶
- Our Fablab had all the materials we needed. However I work at our fablab, so I know where we purchased our supplies from.
- The official currency exchange rate is US$1 = TT$6.8 (Trinidad & Tobago Dollar). However when importing with shipping and customs and duty and taxes we use US$1 = TT$10 as an approximate true landed cost.
- The prices listed here are the prices we paid when we last restocked on these items, and reflect any bulk pricing or discounts applied at the time.
- The prices listed are for the total price for the quantities used.
