__________________________________________________

These drawers use GEN2 rails much longer than the standard GEN2 Lack drawers providing those with larger printers (about 300mm x 300mm) even greater storage capacity. These large drawers are part of the GEN2 Modular Storage System I designed which features a simplified installation method that allows you to rearrange and customize layouts in minutes.

Originally designed for the “Original Prusa i3 MK3 ENCLOSURE…", The Lack drawers have found their way on to many desks, workbenches, and other tables as well. Now with the GEN2's rail design you can quickly swap the storage units between work areas.

Features:
• Gen2 rails allowing quick and easier swap-ability and combinations of many Gen2 Storage System designs.
• Lack Drawers also include optional slots for magnets allowing drawers to snap into place with a nice "Click".
• Drawer stoppers keep your drawers from attacking your feet.
• Designed for larger and easier to install wood screws over the original lack enclosure drawer design.

**HARDWARE**
• Screwdriver
• Countersunk woodscrews: (Metric: 4x25mm to 4x16mm) or (SAE: #6 or #8 up to 1" long)
• Drill bit that is smaller diameter than the wood screws
• Pen, Marker, or Scratch Awl
• Magnets (Optional): 10x5x2mm or 10x2mm
• M3 nuts
• M3 Screws M3x6 - M3x10

**INSTRUCTIONS**
_ *See video for basic instructions_
 • With a marker or pen use the GEN2-QL rail to mark the hole locations on the surface you are mounting.

• Drill out marked locations using a drill bit smaller than the diameter of the wood screw you will be using.

• Prep the rail for installation by installing M3 nuts into the hexagonal holes. You can use a M3 screw to position and tighten the nut in place.

• Install the rail using wood screws, use at least 4 screws on the outer corners to mount the single rail and and 6 to mount the double rail. (extra screw holes are available if you plan to stack more than 2 rows of drawers or contents of heavier than normal weight.)

• Prep the drawer case for installation:

• Install GEN2-QL (QuickLock Mechanisms) These will allow you to quickly lock and unlock drawers without the need to screw them in place with a rail lock.

- Install optional magnets if desired 
NOTE: you only need to install at least one magnet, you can choose to install 2 stacked if you want more magnetism between the case and the drawer. Pay attention to polarity, they can be corrected later if needed.

- Install optional nuts in drawer case (these are only used if you are installing a shorter drawer beneath this drawer case.

- Install optional drawer stops by pressing them into place as they are friction fit. Pay attention to the orientation, notch facing down and towards the front to pass through the slot. The one labeled “L” goes on the left side of the case and “R” on the right side. (While facing the front of the case)

**OPTIONAL - Alternative method for locking drawers** _(You do not need this if you are using GEN-QL QuickLock Mechanisms)_
• Slide the case into position until it either stops or lines up with the front of the rail. (If you feel any resistance you might need to clean up and plastic imperfections around the male or female rails. 


• Slide a rail lock into the rail found on the backside of the drawer case, slide all the way to the top until it buts up against the hole in the rail that contains the nut. Screw in place using a M3x8 or M3x10.

• Prep the drawer, install the optional magnet, pay attention to the polarity. (If you need to remove the magnet you can use another magnet to pull it out of place or use a small Allen wrench or paper clip inserted into the hole below it.)

• Insert the drawer by tilting in back when installing in order to pass by the drawer stopper notches. The drawer should now slide into place.

• I guess you're all done unless you want to make more drawers :)

Installing Drawers under each other

• This is the same process as above but instead of mounting the "Rail Lock" into the nut on the rail you will need to slide a “Rail Lock Upper” into place on the back of the case above or if installing a shorter drawer line up with the hole in the case above it.
NOTE: You can only install the same length or smaller drawer case under each drawer case.
