About this 3D model

The is the revamped edition of my original design, found here: http://www.thingiverse.com/thing:394306. Designed as a linear scanning device for a fiber-optic carbon nano-crystal detector. New features include: - guidance rail for shaft - fewer moving parts; simpler setup - dramatically reduced slop on moving axis (accurate to .5 mm) - greater travel range (4.5 cm) - small cavity under controller mount to store excess wire - fiber clamp at end of shaft Find more info and discover some of my other projects at my blog: http://teamctrlaltdelete.weebly.com/ Questions about application or assembly?
