Summary

Ok I loved the original creepy crawlers toy
as a kid.
Spider was always a favorite.
Now with the magic of 3d printing and oogoo
I get to make creepy rubber spiders with my son!
oogoo - http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/

Instructions

Not printed as yet , will update when printed.

I print in ABS for the molds, I have not tested oogoo in PLA.
I used a 10% infill and the finer a slice the better.
Also i have found that acetone wash on the mold cavity
makes a smooth surface which looks great on the castings.

this is a open mold, pack and if desired use a wax paper to
make a smooth flat bottom on the casting

oogoo is silicone caulking (the cheap stuff that smells like vinegar)
mixed with cornstarch.

when you say acetone wash makes the mold smoother do you mean smooths out the layer lines ?

I have now moved on to using the hot acetone vapor wash.
it will momentarily melt the surface which will smooth the layers.

Worked great with PLA.  I sprayed it with a little Pam cooking spray and it released fine.  It was harder to get it off the wax paper.

 That's freaking awesome feedback!
PLA is becoming my only option
a cold garage and ABS are not a good combination!
i guess the wax paper is not the best idea,
i am looking over the old creepy crawler molds
and will be adding those and a few other ideas for molds.
really do appreciate that others are trying the oogoo
i think it's the best thing since 3d printing, makes it affordable
to make molds and then lost wax-metal, plaster, polyester resin (the fiberglass resin) and a slew of other casting
compounds a few steps from 3d printing!
