I've ordered myslef a QU-BD one up and given its similar build volume to the printrbot simple and low price point, am considering converting it to a 3DR simple. However I am on a budget (as I'm sure many are) and was curious to know what the price would be to upgrade. After looking around I was unable to find a full BOM so I decided to make one in Excel. I thought I would share it here in case others find it useful. It includes everything John has posted in his tutorials such as printed parts, electronics, pricing, where to buy etc... The only thing not included are the parts for the extruder as there are so many different options out there. If you notice an issue with the BOM or find something is missing, please feel free to mention it so that myself and others have an up to date BOM.
Nice work on the spreadsheet!
I don't know what everyone else's experience has been, but my Misumi smooth rods have started to rust. I've since added some oil to the rods to clean them up and prevent additional rusting, but you may want to look to see if they have rust-resistant material available or source them from a different vendor. Granted, I am in the high-humidity environment of South Florida, but I have smooth rods on my RepRapPro Mendel as well and they've been in use for over a year now without a spot of rust on them. The only other thing I can think of is that the smooth rods were a very tight fit in my frame and I took off some kind of finish or scuffed them up during assembly.
As an unrelated side note, I've put up a blog post with some pictures and videos from my build for anyone who is interested: [www.jiggywatts.com]
