I designed this enclosure as a lighting control box for "maintenance" LED lighting strips mounted to the right hand Z-Stage support of my MakerGear M2 printer. The lighting provides illumination for cleaning and lubricating the Z-axis mechanism and guides as well as during Z-axis stop adjustment and bed leveling. The control is just an on-off push button since the lighting is only used during offline maintenance of the printer as opposed to the "operational" lighting I have also installed and which uses relays so that the on-board processor (via G-Code) or interface PC (via serial) could be made to turn the work lights on and off at different stages of printing (potentially in response to sensor inputs). Haven't implemented remote control of the operational lighting yet, just put hardware hooks in place so that it could be interfaced in the future.
Operational lighting details can be found here:

Designed and Modeled using:

• My eyeballs ;)
• AutoCAD
• FreeCAD (to rotate the STL so as to have a minimum of support while printing)
  The box has penetrations for one 10mm diameter switch and two 8mm DC power connectors (input and output to the push button switch). There is space on the front surface to drill another 10mm penetration (for perhaps another switch) and to drill another 8mm penetration on the back surface (for perhaps another power output for more lights or etc.).
  The box is fastened to the right hand Z-Stage support of the M2 by a length of 6-32 all thread rod through a pre-existing hole in the Z-Stage support using nylon lined lock nuts, one of the nuts being captive via countersinking into the box. The top of the box is braced against the bottom of the operational lighting control box, hence the need for only one connection point.
  Print with support (just a wee bit is needed for the nut countersink).
