Details needed, please.
Which one did you get? ABS or PLA? Any mods yet? (DO use a glass plate). How hard is it to keep calibrated? What modeling software / slicer / firmware?
I've been using a Soldoodle (no link. google it) to do various pieces, and it's a temperamental machine at times; some times perfect prints, other times not so. But I hear that's par for the course when you are trying for something really nice.
First on my list would be the bonk-head stick topper. I'm sure that will be seconded shortly.
Second is a replacement controller casing. For those cases with stripped out / broken screw posts.
Heck, while we're at it, how about a whole new controller, with microswitches instead of those rubber pads
And for those folks who want to use shapeways....Check their prices. Our quote was $50 each for a 6x6 replacement cd plate. Which takes about 4 hours and $1 worth of ABS to print. It probably looks a nicer than our prints, but $50....Not that nice.
