About This File
I drafted a TDP dome based on the plans from the forum using Fusion 360, diameter 500mm, height 190mm, arc radius 260mm. I used the revolve function from a sketch to get the dome shape then punched a hole in it where the eye is to go. I split up the dome STL into about 17 pieces (the number varied with on various attempts) using Meshmixer (top tip use plane cut with Cut Type - slice and Fill Type - remeshed fill.
