Printed parts to go with Ormerod sensor board
To use the Ormerod sensor board you will need to print three parts:
1(a) Modified x-motor-bracket3.stl: Modified x-motor bracket. This includes an extended x-homing tab to suit the new position of the IR sensor head. Not needed if you use a microswitch for x-homing instead. Thanks to johneato for providing this.
1(b) sensorpad.stl: As an alternative to printing the modified x-motor bracket, you can print this add-on sensor pad and attach it to the original X motor bracket. Thanks to stevelup for providing this.
2(a) Modified heatsink-duct12.stl: Modified heatsink duct. This includes the mounting points for the sensor board.Thanks to johneato for providing this.
2(b) one-piece-hotend-airduct-with-new-irsensor-2.stl: Modified version of Matt's one-piece heatsink/fan duct. Thanks to Matt (iamburny) for modifying his design to add the supports and mounting holes for the sensor board. I have further modified his design by replacing the T-shaped cable tie point at the top centre by a cable tie loop at the top right, and making the cable management piece stronger. To use the one-piece duct you need to drill an additional hole in the heatsink so that you can rotate it 90 degrees.
3(a) Insulator.stl: This prevents the board from shorting against the z-threaded rod or other metal parts if the print head moves beyond the intended x-homing position. Alternatively, for kit 2 or 3 you can use Kim brown's safety cover, his files are at http://www.thingiverse.com/thing:272634.
3(b) Insulator-for-ultrasonic.stl: Thicker insulator which includes a holder for the ultrasonic transducer. This is thicker and longer than Insulator.stl to ensure that it touches the Z-nut trap before the ultrasonic sensor touches the threaded rod. If you use this part, you may have to extend the x-homing tab even further in the X-direction than the modified x-motor bracket already does, for example by sticking a piece of white card on top of it.
3(c) Insulator-thick.stl: Thick insulator, for use when the ultrasonic sensor is glued on the pcb behind and slightly to the left of the IR sensor.

BoardHolder.stl: This can be fixed to the back of a solder stencil, allowing boards to be accurately aligned with the stencil prior to application of solder paste.
