1. I have received a 3d printed dactyl manuform, and i have realized that most of parts used to hold the kailh hotswap socket is broken. So I want to know which glue is safe for plastic ( it will not melt the plastic ) and can be strong enough to prevent the socket from fly away from the case.
  2. Can I use Type-C USB 3-18V adruino instead of Pro Micro USB adruino? Because as what I can see, the specs of two adruinos written on the chip are nearly the same:

(-) Pro Micro USB adruino: ATMEGA32U4; -MU; 2147E; 2147YHE PH

(-) Type-C USB 3-18V: ATMEGA32U4; -MU; 2216E; 2216QG7 PH

    To question 2: the Elite-C was explicitly designed as a drop-in USB-C replacement for the Pro Micro (same pinout), so that’d be a safe option

    1. What kind of plastic? If PLA 3D Gloop PLA works amazing. Otherwise hotglue, or my suggestion is don’t do single key pcbs / handwiring (ad) I make flexible pcbs for curved keywells (specifically used them on my dactyl keyboards I’ve sold, hundreds in the wild without any issues! www.skree.us or etsy.com/shop/thebigskree if you’re interested in that. (I ship internationally but it can sometimes take a while to arrive).

    2. If the micro controller works with the software (ZMK / QMK / KMK etc) then yes, it works. Both of those would work.
