This is a simple net needle/shuttle which can be scaled down in your slicer to suit whatever job you have at hand. The STL attached will print a 280mm long shuttle if printed diagonally on a 250 x 200 mm nominal print bed.
If you require a more sturdy shuttle, simply scale the Z height in your slicer to add depth to taste.
Simply scale it down for smaller sizes. I printed this in PLA, 0.2mm QUALITY in Prusa Slicer.
For what it's worth - this one will hold 20 metres of 3mm paracord.
