Instructions

I use the XYZ Da Vinci 1.0. I designed it in SketchUp and it doesn't seem to import into the XYZ software and slice cleanly. Instead, I used Silc3r and
exported to .gcode, edited the header to include the Da Vinci stuff, encoded into Base64 and saved as .3w. It printed perfectly.

I'd imagine if you had Repetier or more open printer, the .stl would work as it should.

Be gentle when clipping the supports from the slider. I used a small file to smooth the edges.

I also used 10-32 nylon thumb screws to secure the bracket to the tank. Make sure you drill out the small holes with a bit close to 10-32. If the hole is too small, the tap will cause the layers to separate.

Make sure you use ABS. Do not use PLA. PLA is a biodegradable carbon source for aquariums and will be consumed.
