Designed to fit the standard (original test fitted - not tried the V2) eLeaf iStick vape mod. Completed from scratch taking measurements and test fitting for a snug but still removable fit. Helps protect the mod and the buttons from accidental firing, also can be used for customisation of your mod - currently finishing off a Marvel Avengers themed one for a present for a friend ;) Approx 3 hours build time at high quality (0.1) on a Flashforge Dual Overhangs printed fine for me in ABS and decent PLA without support or cooling - YMMV of course. Tiny bit of sag was easily cleaned up with a craft knife. Model is quite thin so watch for layer separation during print due to cooling layers. Though this does lead to minimum shrinkage with ABS. The fit is about as perfect as I could get and tried it out on two iSticks with similar results on both in both ABS and PLA attempts.
