HSSRHR: Halogen spotlight system rail holder replacement
by Schorhr, published
Nothing special, just a replacement part... but the first useful thing I printed with my Printrbot LC :-)
This replaces the plastic holders seen on one of the pictures.
Fixed with Netfabb's cloud service as my model in Sketchup was a bit sloppy. The more recent version "4e" was just fixed in netfabb studio basic and still has some issues, but prints fine (on the printrbot/slic3r0.9.7).

Print so the tube points sidewards (standing on the "U" shape). Printed with Printrbot using Printer Interface & Slic3r 0.9.7 .4mm, double speed or so, support (45°, 4mm spacing or so)
Clean the holes with pliers or drill them out. I am still trying to figure out the settings, but for a part printed on relatively fast speeds it turned out pretty good.
UPDATE: Print version "4e", it has a bigger inner hole so the screws will sink in better, and the C shape is extended further. It is now a tighter fit but will hold the rail really well. Warning: The gcode file was created for PLA 185C° and a printbed of 120x120/ mid@60x60, use at own risk. The support setting could be better (under 30°/~20° angle, 4mm... will create some support inside the holes, but can be cleaned out with a screwdriver and pliers).
