IKEA Lack Enclosure Offset Hinges (Easy remove door and refit)

cults3d

During my quest to build a Lack enclosure, I found it challenging to locate hinges that would allow a door to swing fully past 90 degrees and facilitate easy removal and refitting if greater access was required, while also not spoiling the clean lines of the Lack. So, I designed these offset hinges which enable a 180-degree opening of the door, along with a simple lift-off and replace feature if the door needs to be removed for greater access. The hinges were specifically designed to work seamlessly with 4mm Acrylic sheet doors. The door half of the hinge features two threaded M3 holes to a depth of 6mm. This allows an M3 x 10mm screw, accompanied by a thin washer, to be passed through the 4mm acetate sheet and tightened from the inside, making the fixings virtually invisible from the outside. The frame half is screwed into the leg of the Lack using 4mm countersunk woodscrews. I designed these hinges to be used in conjunction with my Lack leg mountings, which are remixes from Thebeetleuk. These can be found on Thingiverse at www.thingiverse.com/thing:2776584. As a result, they should work seamlessly with either setup. To ensure proper function, simply make sure the hinge pin centre is sufficiently beyond the outer face of the leg to allow the hinge to open flat against the outer face. Note that you will need to notch the door to accommodate the frame half of the hinges. This requires cutting a 20mm x 8mm area accurately with a junior hacksaw and filing it to the finished dimension. For accurate marking, refer to the drilling jig in the files section. Update: I have added a drilling jig to the files section to facilitate precise drilling and cutting of the door. To use this jig, place it against the hinge edge of the door at desired positions for the hinges. Ensure the jig is positioned on the inside face of the sheet as it is orientation-sensitive. Keep the stepped edge aligned with the edge of the sheet and drill through the jig using a 3mm drill. At the same time, scribe around the jig from the stepped profile onto the acrylic. Remove the jig and draw a line to join the two inset scribes, which should result in a marked area of approximately 16mm x 20mm. This will give you an accurate marking to cut the clearance notches in the sheet. Beware that the jig is slightly asymmetric to provide extra clearance to the lower portion of the hinge (frame element). While this may not be noticeable to the naked eye, the jig will ensure the correct profile for cutting. Before attaching the hinge to the acrylic door, drill the acrylic sheet screw-holes out to 3.2mm to allow thread clearance. Update: I have added a left-handed set of hinges for those who prefer to hinge their doors on the left. If you encounter any issues, please feel free to comment. Your feedback, whether positive or negative, would be greatly appreciated.
