Light Reel / Christmas/Fairy Light storage
This one should fit most lights, even longer icetacle lights. (I have a 20m icicle light on mine)
Its 250mm wide to fill up most of the buildplate and 200 high including the handle. 7.5mm thick so its very sturdy and will last many years to come.
I printed this with PETG as I store it in a shed that get very warm during summer (Australia). Depending on how warm it gets where you store your lights PLA will will work just fine.
