Here you will find information concerning our Ultimaker 3D printer, and projects we're making with.


The Ultimaker is a large build volume (210x210x220mm), open source 3D printer that is reliable, fast and affordable.

Howto: change a filament spool

Changing a spool on the Ultimaker can be tricky if you're not familiar with their material feed mechanism.

First thing to know: the extruder head has to be hot to be able to remove the material.

Lift up the black injection molded part by pushing the lever mechanism:

Then put down the lever mechanism and change the filament:

Custom upgrades

Filament spool holder

The Ultimaker comes with a filament holder, but we've bought new spools that don't fit in. Thus we've made a custom spool holder, using skateboard ball bearings (cheap and strong):

Fan Duct

The Ultimaker comes with a fan holder, but sometimes it unfolds by itself and destroys the print. Thus we printed a Fan duct by Maurits and replaced the original part:
