Print off the connectors add pieces of 8mm dowel and away you go. There are 3 connectors for the branches, all at different angles so the you can change the branch configuration for a different look. Long trunk, short trunk, leaves or flowers? It's all up to you.

Base comes in 2 pieces for easy printing with no support, just slot the stem piece into the base.

I printed everything expect the base at 0.15mm
