Using the OpenSCAD customizer, you can customize (see also section below):
You can add a big heart ♥, smiley ☺ or other special characters (†←→↑↓◄►♪♫☼♀♂♦♠♣∞#!?$%&*+@) now to the left or right of the text! And you can choose also special characters, like pen, clock, key, pin, star, gift, thumbs up, thumbs down, cogwheel, mail, cake, person, Instagram, cloud, book, speaking bubble, puzzle piece, shopping cart, cloud download, boarding pass, trashcan, circular arrows and many more.
You can have 2 lines on top of each other (as requested by schoonke), or even 3 lines (as requested by blitza700). To configure, leave some "textstring" variables empty, and there will be less lines generated.
You can add magnets, as requested by leostevo. You can select sizes like a Cube 10x1, Cylinder 8x3, Cylinder5x2.5, Cylinder8x1.7 or Cylinder12x2.5. Also you can embed them in your print by increasing magnet_closing_layer to 0.2mm, as requested by Mavi222, check out his make for more info.
"HiddenText" and "HiddenTextSize" will generate text on the underside of the base of the nameplate. Use it for notes, dates, hidden messages, etc.
The roundness: Set "faces_segment=2" to have a quick preview in the customizer on this webpage. Once all is OK, set "faces_segment=8" to make the final render.
The shown text.
You can set "Bold", "Italic", etc, for each line. It must be supported by the text you selected though. (e.g. Bangers does not support it)
The font. Nice is e.g.: "Orbitron", "Bangers" or "Luckiest Guy". You can set all fonts (top line, bottom line and under-base-text) separately. By default, all are same as "fontname1".
Each lines font size individually.
The angle where the text is cut (lower angle will make printing easier)
The distance between the lines
The type of base (round, minimal_straight, pedestal, chamfered_rectangle, rectangle, rounded_rectangle). Thanks to rlsmith46 and bratoff for the idea. Use "minimal_straight" if you want to print the text face-down.
Wether you want the text up (to put it onto a table, etc) or upside-down (e.g. to stick it on a wall)
You can print caps for the text to glue them on top. Just set part_to_generate="text_caps". This was mrcpu's idea and request.
You can add "swiss-cheese" holes in the base plate. This is an experimental feature for TheprofessorODK to add metal spikes to the model.
If you could take a picture of an actual print, please "comment" and attach the picture. - I am curious to see your uses in the wild!
