Carbon Fiber parts from 3D printed molds

http://ift.tt/29zZftn http://ift.tt/2a3MmXo http://ift.tt/29zZ3dV http://ift.tt/2a3M032 I would share what i’ve been working on. i’m 3d printing molds in PLA, and making plugs in PVA. wrapping the water-soluble PVA in the carbon fiber using a wet layup, and then encasing them in the PLA molds. (which are coated in liquid PVA mold release before hand)the results are pretty good. finish is pretty much the same as the 3d printed part. extremely strong. this part is 3 layers at about 0.85mm. it will be the top tube for a bicycle frame. http://ift.tt/29zwEYc

Modelling program help… simple shapes with very specific measurements

So I want to design something similar to the attached (I made it in tinkercad, but In the highlighted blue area area I am unable to get a claw like shape…(basically the equivalent of a lego mans hand instead of a block) Ie the plan is to have it clip onto the axle. Would anyone have a suggestion on a software that allows me to get small details (1mm etc) and relatively easy to use?http://ift.tt/29tzk4E you VEditAwesome advice guys Thank you http://ift.tt/29zYIYu
