3d printing adventures volume 2. Part 1: door stop. Random model I downloaded was too big for my printer, so I shrank it without measuring. Shrank too much, so had to design and print a little pad to glue on. Well it works.

It’s $23 for 1kg roll of filament, and the piece weighs 33g. Let’s say 7g for losses/scrap. 40g works out to $0.92. Max power consumption is 120w, and this was maybe 3h total for printing the two parts. So 0.36kwh. CA average is 0.16c/kWh so 0.0576 =~6c. Add 2c of glue: $1 total

Wow, thanks. Much better than I expected. So, although right now there's the cost of the printer, computer and many hours of time needed to get to the point of "just print this random thing I need", there is a conceivable future for 3d printers. But how to get there from here?

The printer was $219 entry level. Plus maybe $30 for tape and scraper. So not much... I’ve printed 100g maybe in 2 weeks. If I get to say 10kg before it dies, printer cost will amortize to ~2.5c/g. My door stop would be around $1.82.
