Openscad file for generating 3d (stl) model of pencil holder with letters wrapped around. Was inspired by 'Tower of Pi' from Thingiverse

rm TowerOfLetters.stl
openscad -o TowerOfLetters.stl TowerOfLetters.scad && echo 'Render done at '`date` | mail -s 'Openscad render finished' [email protected]

Render proccess can easily take 24 hours or more. Then, fix model with netfabb and slice with Cura 15. I used Cura instead of Slic3r because Slic3r generates strange supports.

• To change the text change content variable in TowerOfLetters.scad. Generated text line is automatically resized to fit content_spiral_length (in mm), so after changing the text you have to check that letters are not too wide or narrow. To check change 'true' to 'false' in the only 'if' and look at generated stl file. If something is wrong, then change content or content_spiral_length variables.
• To add a solidwall change text_backplane_deep=1

• Add a normal text
• Add a resize on image surface instead of static scale factor (resize([2*text_r,2*text_r,_stand_picture_deep]) + add margin on image itself)
