A nested pencil case, which locks using a pencil.
A ruler that can make more rulers out of pencils.
A pencil top connector, to construct geodesic shapes out of pencils.

We like pencils!!!




EDIT 14/09/13 : Enlarged pencil case loops and replaced stl.

Print :

  1. 2 x Pencil Case Halves.
    • Cable tie or PLA rivet together.
  2. 2 x Rulers to make a press mould.
    • Insert pencil, press together in a vice and viola, a pencil ruler.
  3. Zillions of Pencil Connectors (and pencils) to make a massive moonbase alpha.
    • Scale up or down to achieve correct fit around pencil.

All based on a standard pencil 7mmA/F x 190mm long.

what did you use to secure the bottom together?

Hi, the instructions call for cable ties or PLA rivets to hold the two halves together.

My print bed is to small to fit this. Would shrinking it affect the functionality?

use pencil to hold it bottom together too? :)

I liked the dessing, it's very original, congratulations!!. i have tried but after print I found near to impossible to open it, and it finally broke. Probably the problem is ABS, the hinges were stuck. I would suggest you make each cover separately, and then pass through a printed screw with some washers, but it woldn't be as funny.

Don't discourage from doing it, just in PLA!!

Sorry you had issues, this is a print in place object not one for multiple assembly, so the design will remain as is.

There is 0.5mm clearance within all of the mating parts in the hinge design. It sounds like you are overextruding , maybe try to recalibrate your printer or slicing settings to achieve this clearance?

i think .05 is not enough clearance for abs.

does it work for abs?

I don't print in ABS, so I don't know. It is long with several thin walls so it may be an issue for some.

Great Design,
But do you have to extract the pencil-case shells from the stl file seperately. or can it be printed directly?
Because it looks like it has to be assembled.

Hi Martin,
There is minimal assembly by having to cable tie / pla rivet each half together, however each half can be printed completely assembled, see the photo showing how it was printed on my build table + instructions tab.

did you use pla or abs, mine shrunk that the pencil couldnt fit through the loops, any suggestions great design for my nephew first year in school

I have enlarged the loops and updated the stl. I figured most Thingiverser's out there would have painted pencils.

I used PLA. As you can guess from my pictures, the "standard" pencils I have do not have paint on them, which left me with a dilemma, do I design this case for pencils with or without paint?

I suggest you can try two things,
1 : File out the holes a little, especially where there is a little bridging and the loops may have sagged.
2 : Scrape the paint off the pencil with a file or craft knife.

Ever thankful for any picture uploads.

I appreciate the response! I will try your tips out on the current one I printed, I would upload the design when I try it out, again thanks hope you win!

Love the ruler design, VERY creative!
