Summary I was inspired to action by the Wagner HT1 base and by the countless things I've accidentally melted setting my heat gun down. This is for the DrillMaster (cheap Harbor Freight) heat gun, which, unlike the Wagner has its vents on the back. I've tried to ventilate accordingly. I've now improved on the original design and successfully printed. Instructions Just print the thing. It does not snap on or anything, so if you want it permanently attached you'll have to use glue.
