Beetle Blocks is a graphical blocks-based programming environment for 3D design and fabrication. It allows writing scripts to control a beetle that can place 3D shapes and extrude its path as a tube, which can then be used to make a 3D print. Beetle Blocks is made by Eric Rosenbaum and Duks Koschitz, with software development by Bernat Romagosa and Jens Moenig. It is based on Scratch and Snap!.

Note Note: Beetle Blocks is alpha software and is currently in development.
An example of what Beetle Blocks can do



Beetle Blocks has most of the same block categories as Scratch. In any of the categories, you can right-click a block and hide it. If you wish to restore the block you must right click the background and select "show primitives". Beetle Blocks has the following blocks, in addition to those found in Snap!:


The motion category
The control category
The pause block
  • go home :: motion
  • move (1) :: motion — Moves the specified number of steps.
  • rotate [z v] by (15) :: motion
  • go to x: (0) y: (0) z: (0) :: motion
  • set [x v] to (0) :: motion
  • change absolute [x v] by (1) :: motion
  • set [z v] rotation to (0) :: motion
  • point to x: (0) y: (0) z: (0) :: motion
  • ([x v] position :: motion)
  • ([z v] rotation :: motion)
  • push position :: motion — Saves the beetle's position so it can be used later.
  • pop position :: motion — Restores the position most recently saved with the block above and removes it.
  • set scale to (1) :: motion
  • change scale by (0.5) :: motion
  • (scale :: motion)


  • reset :: #505050 — Clears all rendered graphics.


The shapes category
  • cube Dim. (0.5) :: #308997
  • cuboid l: (1) w: (0.5) h: (0.3) :: #308997
  • sphere Dia. (0.5) :: #308997
  • tube l: (2) outer: (1) inner: (0.5) :: #308997
  • text [hello] H: (1) W: (0.5) :: #308997
  • 2D text [hello] size: (10) :: #308997
  • start drawing [lines v] :: #308997
  • stop drawing :: #308997
  • start extruding [curves v] :: #308997
  • stop extruding :: #308997
  • set extrusion Dia. to (1) :: #308997
  • change extrusion Dia. by (1) :: #308997


The colors category
  • set [hue v] to (50) :: #653d7a — Sets the hue, saturation, lightness, or opacity of the beetle's color.
  • change [hue v] by (10) :: #653d7a
  • (color [hue v] :: #653d7a)


  • request user input [] :: #828282 — Asks a question and stores the answer in (answer :: #828282).

Make a Variable

The make a variable dialogue box

The "make a variable" button takes you to the variable creating dialogue. In this dialogue you can input the variable name and select if you want this variable to be available for all sprites or only for the one that you are currently creating the variable in.

Make a Block

The make a block dialogue box

The category My Blocks has no blocks until one is created. To create a block one must click on the Make a block button. This will open up a dialogue box which will give you a selection of customization options.

  1. The first one gives you a selection of category. The color of the block varies according to the category that has been chosen.
  2. In the second one you can select a name for your block, which will be written on the block.
  3. For the third option you have the ability to select between three block types: Command, Reporter and Predicate.
  4. The fourth final option is whether the block should be available/visible only for the sprite that the block is currently being created in or whether it should be available/visible for all sprites.
