lib3mf-dev 1.8.1+ds-3 (amd64 binary) in ubuntu focal

 As 3MF shall become an universal 3D Printing standard,
 its quick adoption is very important. This library shall
 lower all barriers of adoption to any possible user, let
 it be software providers, hardware providers, service
 providers or middleware tools. The specification can be
 downloaded at http://3mf.io/specification/
 .
 Its aim is to offer an open source way to integrate 3MF
 reading and writing capabilities, as well as conversion
 and validation tools for input and output data. The 3MF
 Library shall provide a clean and easy-to-use API to speed
 up the development and keep integration costs at a minimum.
