The previous case sucked, never stayed together properly. The new case is great, a single piece except for the lid, which snaps on with the power of magnets. I've also added a push button to calibrate the red light distance because I was making one for my dad and it's a bit much to expect him to reflash the firmware if he wants the trip distance changed. The setting will be saved in EEPROM, so will last through battery changes.
