Thermistor had a dupont wire but board had a XH2.54 port.
This piece is a converter to use the crimp connector from a dupont connector in an XH2.54 shell.
Might be material stuck in the hole & tolerances are quite tight.
Printed with 0.15 mm layer height
The author remixed this model.
Used this model as a base XH2.54 female connector.
