A box to hold the PCB of a DIY timer kit (MK111) based on the 555 timer IC. The lid snaps on tightly. Intended for mounting on a dual camera rig such as the Titan 2 Rig. Published under CERN OHL.

Details and full instructions are at the KAPtery.

The long dimension of the box should be 6.9 cm and the long dimension of the top should be 7.35 cm. The tabs on the box top must be strong enough to flex a little without breaking. So make sure your slicer does not make the tabs hollow and use a high enough temperature to ensure good bonding. More details and printing instructions are at the KAPtery.
