It's not ALWAYS that cheap. I kept the costs down as much as possible. PE ain't cheap, so... And I did the math wrong. It's not 6%, but closer to 9%. Too early on a Monday morning to do math... So, that's still only $4.32. Now, I'll be honest, if I was selling JUST the resin parts, I would be charging more than that, something like $10. But with the PE, it's to keep the overall cost reasonable. While I do this to make money (it is in fact my day job (and nights, weekends, holidays...)), I really want to get these out there for people to enjoy.
Also remember that the price doesn't just reflect the cost of materials, but needs to include the labour involved as well. People sometimes complain about an add-on part costing $20 or something. While it would take them 4 hours to scratch it themselves.. So, at minimum wage (here in Ontario, Canada, that's $11/hr), plus materials... Well, that's MORE than $20. Plus, who gets it right the firt time anyways?? So, 2x 4 hours... :facepalm
