Hi there, you can use free software like autodesk’s 123D or tinkercad. If you don’t have the time to work yourself into the CAD software (which shouldn’t take very long), then I could model the parts for you for free. Just contact me via my hub at : www.3dhubs.com/siegen/hubs/marius Cheers, Marius Breuer
Well modeling a splitted pyramid with a cylinder inside isn’t such a difficult job for me, but for someone that never worked with CAD software this might take hours. As this is his first order, I’d like to give him a nice start
I would recommend learning how to use CAD as part of your 3D printing hub, a good basic engineering know how is also desirable! so crack open those engineering text books! lol.
