Using a soldering iron involves having a little wet sponge pad to keep the tip clean. When using the soldering iron, you want to wet the cleaning sponge first and so you have to drop water in the tray, maybe spilling it, or having to go and find water somewhere else first... At least this was my issue and I got around this designing this pad holder with a little reservoir incorporated. Just fill it up once and it will be good for a while, just tip it upsidedown when you want to wet the pad and it's done...no spilling and no fetching water. When tipping it, hold the sponge with your fingers and with the thumb gently press the bottom. I printed it with clear PLA so I can see how much water is inside. You can customize the size of the reservoir, the pad holder and if you want some side pads to screw it on something heavier, or you can just put some weight inside...for me the weight of the water inside is enough to hold it when I wipe the iron tip. ---------------------------------------------------------------------------------------------------- I created these eBay links where you can find components, filaments and spare parts at the best prices.
