Add little notch/groove between bottom/top lid? #3

Open dragetd opened 6 years ago

dragetd commented 6 years ago

My first print in #1 fits pretty tightly, since the bottom case flexes a tiny little bit because my PCB holes were ~0.2mm off (fixed in my current branch).

But generally, the top part is just 'resting' on the bottom part. What do you think about adding a little groove around the lip that would click into the bottom part?

I would give it a try to modify the case.scad and use a 0.5mm cylinder + a cut on the bottom side that makes the two halves clip together. Any thoughts on this?

Mmh. Have you tried to reduce contact_padding in case.scad? My printer is pretty cheap, so I had to use a >0 value for parts that are supposed to touch. It could be made configurable by the user, but since I could test the print only on my printer, some settings might be more appropriate than other for other printers.

It fits pretty neatly. But it could have a satisfying click. =D

Tho, this idea, just like the others are postponed for me till February. If anyone else wants to have a go before me, feel free!

A previous version was actually designed with a complex clicking system. Unfortunately, given how thin the whole box is and how precise my printer was, it was meaningless complexity. Basically, it either had no effect in the best case, or distorting the whole thing (because the clip wouldn't fit in the mess the printer did).

There are several cases on Thingyverse and elsewehere including a notch to 'click' together pieces. Most recent printers are very much capable of the needed precision.

This would be still a very cool addition. :)
