Holes with NO Support

thingiverse

I have been working on a method of printing fairly simple designes, with holes, WITHOUT support material. So Far, I have had quite good results. HOW, I hear you screeeeeemmmm !! AS the print gets just befor the piont at which it would 'string' over a blinde hole, (as in the STL file) fill it with blu-tack, simmilaly, as can be seen in the photo, a slug af blu-tack has been added (needs to be a bit longer). as the print progresses to crowning point, squeese the blue tack, to fill the hole a bit tighter ... WARNING you will get burnt if you hesitate .. *** if you are clever, then you can edit the G-CODE file, to move the head out of the way, for a short pause. dont wory too much if you miss, because the head will push the blu-tack out of the way.
