Drip Tube Spike 3mm

I needed a spike to hold the Blumat Tropf 3mm drip line that comes off the carrots. These spikes can be printed in just about any material, I used Silk PLA for this test print and it came out fine. 

I used 2 shells, 3 layers top and bottom, 15% infill with gyroid pattern. 

The U of the spike is actually 3.5mm internal diameter, this is because the OD of the 3mm tube is about 3.48mm.
