Long extension for GoPro camera. Some design for manufacturing has been done. Design has been tweaked to print clean on my TOM. If these work for or don't quite fit please let me know so that I can see if the design could use an update.RA = "right angle" version.Print with support. Watch the layer count to make sure the gap thickness is about right. Some skeinforge settings will cause an extra layer to be added that will suddenly make the parts not fit.Found a chisel worked great for removing the support. If they don't quite fit a small file works great to open up the slots to make the fit just right.
