printed one more, purple this time, love them. i use 35-40mm band, they are not adjustable, i do not need it, but even when i close them based on my head circumference, pretty much any adult can wear them with no issue, even 9 years old kid was wearing one and it was not loose, i like wider bands, they grip better, they do not need to be as tight, and they come in many cool designs, . they also eliminate the need for top strap. imo.
i used 0,2 layer this time, it saved 3 hours on printing, and unless you are really looking up close, they don’t look any different. i took me half a dozen of fails before i diled right settings with esun petg, now it seems to be printing pretty good
if you ever feel like it, and have time could you make the base wider for 35mm band, just the base , grips are fine the way they are. now it has folds under the base plate, which isn’t really a big deal, but it would be more comfortable without them, again if you ever have time and feel like it, imo wider band really improves the experience. with your holder\wider band, and new driver this cheap light is really turning into a very good one.
one thing, you got to print them on the side, if you print them flat, grips snap as soon as you try to put a light the first time, but with layers running along the grips, they flex just fine. side printing requires supports, that leave bad finish, but they are only inside the grips so you do not see it when the light is in.
