This is the convergence of all of my interests: bikes, 3d printing and shiny things! I saw it featured over on Hackaday, but it’s just too good to not repost. This is a bike built up from carbon fiber rods and laser-sintered metallic lugs. There is a whole lot of awesome in that sentence. I’m …

Nail Files – Reprap tools list
I’ll admit it. I went into cvs and walked out with two packages of nail files and a snapple. What of it? Despite the weird looks from cashiers, nail files are absolutely _perfect_ for cleaning up prints. You can do fine sanding, clean up seams, or round off those sharp corners from a kapton heated …
reprap tools shopping list – Irwin self-adjusting wire strippers.
I’m really excited about some tools I have found recently, so I figured I would start a recurring series of posts about them. There will be some simple cheap ones, and some expensive ones. Hopefully they are useful to someone else! If you want a sneak peek, then you can check out the amazon list …

Why Kapton rocks
I have never been a big believer in using kapton tape as a heated bed surface. I never saw much benefit, and whenever I used it I ended up cutting it or scratching it very easily trying to get the parts off. When I use blue tape I generally heat the bed up to 90-110. …

Advice needed for Makerbot rebuild

Direct drive Extruder gear
I’ve been on the lookout for the same kind of gear that makergear uses on their extruder for quite a while. Not the gearhead for the motor, but the actual part that bites into the filament. I found cornwall model boats this morning, and I ordered a few from England. It appears to be a …
Boston Reprap User group meeting
I’m trying to put together a meeting of people interested in 3d printing. It’s called reprap because I think most of the people will come from there, but makerbotters and professional printers alike are more than welcome! I’ve got a post over on the reprap forums trying to get an idea of how many people …
makergear prusa z-axis fine adjustment screw detail
The makergear google doc only has a mention of this adjuster screw. I was really confused regarding what they were talking about. I finally saw it in one of renosis’s flickr pics and I decided I would take a closeup to show it in all of its glory.
