Mendelmax 2.0 / Enable Raptor Hand #2

More parts on the raptor hand build. 


Finger bits.



Not assembled correctly but you get the idea...






Rest of the parts done. The tensioner block is on backwards but you get the idea.







Starting to run the strings.



Running the elastic.



Tensioner block.



Looks pretty messy...



But cleaned up nice!









Still working out the kinks but it seems to function pretty darn well.  I'm guessing I have about 2 hours of time into the build, and that includes getting the printer set up and clearing the parts.  I did it 3 prints of about 4 hours each (with some extra parts).  I think with some practice I could crank one of these out a day if I got the printer started in the morning and did all of the parts in a single batch.  A larger nozzle would sure help speed up print time.  Guess I know what to put on my wish list!

Playing around again. Downloaded the Raptor hand from Thingiverse. Got most of the parts printed. I *really* need to get a .5 nozzle, it's taking forever. I think I'll have about 13 hours of print time into all the parts by the time I'm done, but I did make a couple of extra fingers and they are definitely NOT an "easy" print.

I tried doing the entire thing in one set but I had some bed adhesion issues. It was going to take waaayyy too long anyways. The first piece I printed was the palm.



Came out pretty nice. I'm still getting some warping on overhangs but everything else seems decent enough. Still not sure why I'm printing at 174 deg. C though (PLA). Pulled my extruder apart to check the thermistor but nothing seems out of place.

Few more pics of the palm.





Worst of the warping.  Maybe Mr. Flood can chime in and give me some more ideas of what to try here?



I thought this was pretty impressive though. Haven't done much with anything that has a serious overhang but it turned out nice.



And the gauntlet. Notice the two slots where it bridged. A little bit of goo but really it cleaned up nice.







Sure is a teeeeeny little hand. Makes me kinda sad- Don't know what I'd do if I lost the use of one of mine (knock on wood)...
