Replacement pulley for roller blinds (IKEA TUPPLUR)

This is a replacement pulley for the IKEA TUPPLUR blinds. The pulley mounts on the wall and support the 'chain' used to roll and unroll the blinds.

This is as close to the original design as I dared to get in order for the replacement one to look the same as the others. It should be possible to make a much cooler design though:-)

Other spare parts for these roller blinds are available:

• Clips: http://www.thingiverse.com/thing:43705 Instructions

Print two of those and they snap together to make the pulley. It works just like the original design but there are some small differences which makes it impossible to snap a printed half with an original half.
