First of all Thingiverse where you can find 1000s of things to build and make


The “reprap host” slicing application can be downloaded from

you’ll need a working Java runtime to use it.
You need to download the config file for our working reprap from:

  • drag the loaded object a little on to the be – about 1 square diagonally
  • press the green ‘Print’ button
