This is a small cage ball that can be a christmas ball attached to a christmas tree

My laser machine cuts this through openoffice wich is a free software. Openoffice can export to other formats but i can't test if it is suitable for your machine. But if you re-worked the plan in a format more suitable for you and send it to me, i will be honoured to post it here.

The .odg cuts 3 balls put two circles in place with the tools and start to glue the arcs once half the arcs are sets and dry, remove the tools (maybe insert another thing in it) and glue the rest of the arcs.

Paint as and if you wish

.dxf are not tested, i "print" directly the .odg with my lasercutter
