Support Material.
The picture of this outstanding build pretty much says it all. Dual extrusion, with soluble support on one print head means you can do any overhang you please. Water soluble PVA is actually more expensive than the plastic you print on top of it, so when designing your support network you may want to economize a bit.
The good news of course is that modern extruder designs are very sleek and can fit onto small bots, and even at that price support is less than ten cents a cubic centimeter, and the PLA itself is less than four, so “expensive” is kind of a value judgement…

Don’t you guys think that having the blog toolbox on every page on thingiverse is a little over-intrusive?
Having it on the front page would be cool, but just not next to every single category, picture and thing.

love the print but i also notice that the warping of the part after the support material is removed still remains.

also, I personaly intend to use pla for support on abs which is way cheaper than pva. still having major issues with generating good dual extrusion code since the firmware/repg seems to barf pretty hard on tool changes.
while it will use E codes to control either extruder reseting the e value doesnt work and changing to a different tool realy confuses the distance values in the A?B axies.
