Sculptr Ninja Top Frame for GT2 Pulley

thingiverse

I opted for actual GT2 pulleys instead of the suggested ones and modified them to fit a GT2 pulley snugly, increasing the bolt hole to 5mm in the process. To accommodate hollow aluminum tubes used for the 175mm cross bars, I added a wire pass-through feature, allowing switch wires to run inside the tubes to the back of the Z frame. The standard tops now have a channel connecting the switch to the tube, while the Z-axis top has a channel running straight back from the tube's interior. A spool holder was not included as it seems impractical for this design. To assemble the modified frame tops, you'll need: 3 x GT2 pulleys with 5mm bearing bores and 3 x 5x30mm screws, which can be sourced from http://www.thingiverse.com/thing:1444028.
