Problems

[steamboat]

If a design for the home printer should be successful, one has to forget all kind of fine and fragile structures. I am a member of a 3D printer group here in Hannover and have seen "some" home build printers and what results you can archive with it - don't expect to much. And even if you have calibrated everything and are using best materials, fine structures can be frustrating.

This in mind I have some fear about the durability of all the crank pins and the worm gear of the actual centipede design. This is only a feeling because I have not build something like this with an 3D printer!

But especially the durability is what a design makes successful. Making Shellmo is one part - programming and using it is the other much longer phase!

Building my RepRap 3D printer I didn't care about using lots of not printed parts because I wanted to get a reliable printer - same with Shellmo!

I am just printing RepWalker in ABS and am curious about the durability of its gear - maybe I will be positively surprised ;-)
