Syringe Cap (Luer lock)

thingiverse

I store my solder mask goo in small syringes so it's easy to apply to boards without making a huge mess. These caps are designed to seal the container securely while not in use. Print Settings Printer Brand: Wanhao Printer: Wanhao Duplicator i3 Plus Rafts: It doesn't matter Supports: No Infill: 20% Notes: Note that PLA is relatively brittle, and you'll need to apply a little force to the middle part of the connector when inserting or removing the cap. I've had good results printing mine using PETG; I recommend using either that or another strong plastic like ABS for best results.
