Quite a lot of work went into it actually, we tried to make fully automated splicer first but it failed due to filament expansion issues. So manual labor is still the king :)  

On the filament sample snapshot you can see results, 1 is manual and 2 is what splicer creates. Of course you can trim manual joint but it is work and will get annoying soon enough.  

You can get Splicer copper parts, kit or fully assembled unit via campaign at our web page.

We work to bring more color options to OSS 3D Printing and have a few other very interesting ideas. Filament Splicer is first thing in this quest.
