The Thermacell Butane cartidges are notoriously impossible to refill - forcing you to buy the refill cartidges. This is an adapter piece designed to utilize standard butane recharging cans.
The adapter is designed to depress the valve in the thermacell cartidge and allow fluid to transfer through the small openings in the valve (see images).
Recommended to print with:
Nozzle: 0.4 or 0.2mm
Speed: Slow / 50%
Infill: 100%
Layer height: 0.15mm or lower
Enjoy trouble free refilling ; )
