Summary

A cool pencils pot full of knurls :-)
(just another example for the knurl surface library v2)
This thing is big! More than 80mm diameter and 120mm height.
The one I printed (PLA) has a wall thickness of 0.7mm.
The ZIP file contains already compiled pots and test files with a wall thickness from 0.7mm to 1.2mm in 0.1mm increments).
Do use the OpenSCAD to change whatever the dimensions you like.

UPDATE: Added "solid_pencilsPot.stl" intended to be printed in "vase mode".

Instructions

Don't be lazy and use the OpenSCAD :-) it may take longer... but is easy and you have full control over all the dimensions.
Be careful if you want to go fast and just scale this thing: scale it up as much as you wish, the walls may be too thin to scale it down, you can always use something like thingiverse.com/thing:32118 to determine your minimum wall thickness for the profile/material you are using.
Do use the test STL before attempting the penci pot! It will not take too long and may save you to have to stop the build 1h later.
OpenSCAD usage:
Change the "user parameters" to your desired values.

  • Tip: Ensure that the pot height is a multiple of the knurl heigth.
  • Note: The base of the pot has a thickness equal to the height of one knurl
    infill should be set to a minimum of 20% for stability.
    Press F5 to render (it will not work but do it anyway).
    Take a look to the console, scroll up if needed until you find the maximum and minimum diameters echoed by the knurl library.
    Update max_diameter and min diameter parameters accordingly.
    Compile, it may (will) take some time, and export as STL.
    Comment the line for the call to "pencils_pot()" module.
    Uncomment the line for "print_test()" module.
    Compile the test and export to STL (it should compile much faster).
    Try to print first the test and check if you may print the pot or you better adjust the parameters before.
    Enjoy!

Is there a way to fill these in completely so that the vase mode in Cura will work?

Either use "solid_pencilsPot.stl" (just made available to download) or, better, use OpenSCAD to make whatever the pot you'd like ;-)

Sorry, but what is the name of the right printed thing?

Sorry for the late answer.
That thing has no name, was never good enough to be uploaded. It's a lead screw that was made with "3 starts lead screw" ( http://www.thingiverse.com/thing:9428http://www.thingiverse.com/thi... ) "Poor man's openscad screw library" ( http://www.thingiverse.com/thing:8796http://www.thingiverse.com/thi... ) and "
Knurled surface finishing library" ( http://www.thingiverse.com/thing:9095http://www.thingiverse.com/thi... ).

I'm new to this, how do we print it on Slicer settings to get only the base covered, while having the center empty? Can't seem to figure it out yet.

Not sure to understand your question, sorry.
For whatever the slicing software of choice, you should use any standard profile/settings, the model has been designed hollow with a solid base. Be aware that the walls are thin, it may be a little bit tricky to print. Hope it helps.

This is one of the best prints I have done. I used the v12 because the thinner versions printed with holes in the sides. I have printed 4 of these in various colours to give to friends. Not only is it useful but it prints fantastic on a Wanhao Duplicator 4x.

Glad to hear that! Thaks a lot for the feedback and makeng them!!
