JohnFox 25 Report post Posted May 22, 2015 in Hollow threads/helix I have just been trying to make a threaded hole. Using Sketchup, I made the helix on its own, copied and pasted it into the object with the hole, then moved it into position. When I exported it into Cura everything worked, except that the threads appeared to be hollow, with only the outer shell on them. They seem to stay hollow even when Cura is set to 100% fill. Any ideas? Not sure if this is a Cura problem or to do with Sketchup. Share this post Link to post Share on other sites
JohnFox 25 Report post Posted May 23, 2015 in Hollow threads/helix I can answer my own question. The problem lies with Sketchup. I was trying to make a thread with a circular cross section, changed it to a triangular one and it worked OK. Cura really does pick out the problems before printing. I don't always trust the 'normal' view but the layers view seems to be 100% correct. Share this post Link to post Share on other sites

JohnFox 25 Report post Posted May 24, 2015 in Hollow threads/helix Thanks for the link. Did the upload and repair but for the life of me I can't download the repaired file. It seems to be a known bug. Are there any other repair programs?
