Dresser Key Holder

thingiverse

I designed this using Autodesk Inventor to fit my original dresser that came with my apartment. It utilizes the long section on top for leverage and provides a convenient out-of-the-way spot to hang my keys. My keychain is heavy, weighing in at ~7 keys plus an aluminum climbing carabiner clip, yet this design can still support it without bending or breaking. If this dresser adapter doesn't fit your furniture, you should be able to easily customize one with a similar design. Take note of the type and size of clip you use on your keys and simply measure it with a tape measure to make necessary adjustments to my design. I printed this object in 2 infills: 40% and 50%. The higher infill density makes it more durable. In a previous version, I printed it with only 15% infill using PLA, which caused it to snap easily. Another earlier print also snapped due to being rotated 90 degrees about the Y axis, resulting in layers perpendicular to the weight force of the keys. By printing this design on its side, as intended, I achieved a much more stable result. To sum up, I recommend printing with relatively high infill density and in the orientation specified by the STL file (on its side). Avoiding supports altogether is also beneficial. I printed this adapter using Hathbox Gold PLA. If you feel comfortable doing so, consider printing with a stronger polymer like ABS, PETG, or wood filament. Since I'm currently limited to printing with just PLA on my $200 printer, that's what I've been sticking to.
