ok curently focusing on the front plate, moving screw points out of finger area, beveling the outer edge, reposistioned the butons to acount for internal parts

curent design asumes that the screws will stick out on bothe sides, this could be solved with a a cone shaped screw hole but you will still see ther screws, my idea was to have a double nut in the center of the device alowing easy acces to the inside, alternative was to glue and snap all the parts togeter that would have made it almoust imposible to take it apart. we dont have acces to injection molding so this is the best i could think off.
(i do relise that the top side is not structerialy sound due to all the holes but the screws sude releave a bit of that


still wip but by all means criticize this design. it realy helps

You should upload your images to something better than postimg, they seem to block hotlinking.

I am thinking about screwing from the backside into the front side by having screwposts epoxied to the backside of the front

No. Using metal or nylon screw posts and epoxy them to the backside of the front plate.

I like the new screws placement, but I am a bit worried that they would be placed in rather weak spots that would make it easier to bend each side of the faceplate. Could the bottom screws be moved a bit more on each side?

Acrylic is impossible to bend, it's too hard. It will break though but that's not easy.

if i move them out more then i need more space mainly for the wifi module, that thing is prety big

epoxy a screw bold will look horrible from the front, and it still not strong enugh the surfice area for glue and epoxy has to be much larger then a screw bold to achive the same strenght
if you do not like the screws on the top l look into screw covers that are comen in furniture to hide screws

Ah true, I was confusing it with some soft plastic. Btw how expensive would such case be?

Well if we sell over 100-200 we will use it as the case by default.

I am curious about how the cheaper case would look like. Would it be possible to do a quick 3D render?

I am sure adekto can come up with a new model, though some things cannot be planned so far, as I haven't designed the PCB yet.

cheaper? wel could just ditch the front plate and just have a sinlge back plate with some nylon spacers, its not prety but it would get the job done

im trying to look for alternatives but i cant find anything that is only cheap at highvolume or is just expensive
