Wiggly Spider Pencil Topper or Pen Clip, for Halloween or whenever

thingiverse

I wanted to challenge myself to design a sort of wiggly bug that could print in place, so I made this. The spider's legs hang on a bar inside the spider and wiggle when the spider is moved. I wanted to make this as a pencil topper, but also then remembered I don't actually use pencils and would like something for pens as well, so I worked out two sizes of pen clip in addition to one to fit a range of pencils. The sizes are: - 12mm, good for most^ larger pens and pens with caps and side clips. (Also those nice wide mechanical pencils with the push up erasers.) - 10mm, good for some in between pens and slim Bic type pens with caps - Pencil size, which is a stacked series of: 8.5, 8.3, 8, and 7.6mm. Fits most^ pencils as well as the end of some standard slim Bic-type pens and gel pens, sans caps. ^(I tested just about every writing utensil I could find in the house. You may also want to measure your favorite writing implement before making a choice.) There is an opening on the pen clips to fit around the side clips many pens and pen caps have; there is a slimmer section of the ring for sliding under that clip for better hold, or the regular thickness for other pens—or you leave the opening where the clip is, depending on the pen and the fit. I have built in some bed anchors around the model to help keep the tiny pieces in place through printing, as well as to be able to add 0-distance skirt lines to firm up the adhesion and horizontal support, and to keep those extra lines off the legs which are a pain to try and clean up. If you want to remix any part of this, I included files for the pen and pencil toppers on their own, the spider on its own, and the three finished models without the bed anchor lines.
