I just posted the detailed bill of materials for the hardware and electronics in my Rep(St)rap. Most of the lines have a comment. The comments and URLs would have made this whole process a lot easier for me, so I hope the spreadsheet helps someone else!
This is the first time I’ve used Google Docs and I must say it’s quite easy to use. I imported from OpenOffice. The conversion of OpenOffice.org formulas failed, but it was fairly easy to sort that out cell-by-cell.
I’m sure some people just want to know what the bottom line was. Well, I paid $555 for the laser cut kit (including shipping), $782 for the hardware and electronics, about $100 for shipping of the hardware and electronics, $100 for 10 pounds of ABS and HDPE spools (including shipping), and $20 for miscellaneous supplies at Ace Hardware. So $1557, and that’s not including the money I spent on new tools (a drill press, 2 vices, a new hack saw, a lot of drill bits, an M6 tap, an M8 die, etc.) and materials I did not use, broke, or forgot to list in the BoM.
Wow, that’s expensive. Buying the complete kit from BitsFromBytes probably would have reduced the price. Still, I prefer this machine and the experience I’ve gained over a big flat panel TV. 🙂
