Teennntacllles… coming out of the waaaaallll.

amyhurst was asking for a key hook by our front door and decided upon a tentacled theme.

guru’s awesome volumetric tentacle seemed like a great choice, so I pulled it into OpenSCAD and made space for a 1” roofing nail to slide-and-lock into the back of the tentacle.

(thanks to cibomahto for the tagline up top).


  1. [Optional] Adjust the SCAD file to match your nail measurements, with some room for slop, and re-export STL.
  2. Print “tentacle-keyholder.stl”
  3. Insert 1” roofing nail (or nail of your choice, if you customized) into the slot and work it back and forth several times to make sure it slides and locks into place reasonably well.
  4. With the nail in place, make a mark on the nail so you know where to stop when hammering into the wall.
  5. Remove the nail from the piece and hammer it into the wall, stopping just as your ink disappears.
  6. Slot the tentacle into place.
  7. Hang keys or your just creep out your guests/friends/roommates.

File cabinet replacement bracket

Time to get organized!

For years I’ve had a pair of metal interlocking file stands in a set of wood drawers for holding files. For almost as many years, the plastic brackets that secure them in place have been broken and useless, letting files flop around at will.

Today, my partner offered a trade: if I fixed the file cabinet, she would do all of the house cleaning. Needless to say: OFFER ACCEPTED. :)

You can tell from the pictures that I’ve got a long way to go as far as quality settings with the PLA 4043D and MK5. The MK5 puts out plastic FAST and the PLA stays hot for quite a while, allowing it to sag. I’m sure I could improve this with some cool settings, a faster feedrate, lower temp, maybe a fan blowing on the work piece, etc. Instead, I padded out the values for the holes and hollow areas with some multipliers in the .scad file and everything works great!


  1. Measure out the clip that you’re replacing.
  2. Update the .scad file (be sure to curse me for the sloppy code) and export STL.
  3. Use Pleasant3D or ReplicatorG to center the object in the STL.
  4. Slice.
  5. Print (x 2).
  6. Screw into place.
  7. File!

Floss Bow v1

A little bow to string your dental floss across. Requires less floss than using your fingers, and only slightly harder to use!

Standard warnings apply:

  • Don’t accidentally swallow this thing.
  • Don’t use this if you’re uncomfortable having plastic in your mouth.

And problems with this design:

  • The bow is not quite thick enough to prevent it from bending inward.
  • The straight-line handle makes it hard to reach back teeth.


  1. Print
  2. String with dental floss.
  3. Floss teeth.
  4. Repeat as recommended by your dental hygienist.
