Aus3D IR Proximity Sensor Mount for MaxMicron Printer

MaxMicron x-carriage adapter for the Aus3D IR proximity sensor Update - added option for complete cover, or lid Can now print a version with a lid. Still can print with no supports, scad file can be edited for either version. About The excellent Aus3D IR proximity sensor board (http://aus3d.com.au, http://wiki.aus3d.com.au/IR_Probe_1.4) is designed to fit standard 30mm E3D extruder cooling fans. Printers that don't have E3D fan mounting points need a mounting bracket. Here is a bracket designed to replace the induction sensor on the x-carriage mounting point of a MaxMicron printer. The OpenSCAD file is given as well so the design can be adapted to other printer mounting points. The adapter is in two parts, a shell and a retaining bar, that are positioned in a single STL to print. The shell has a space to allow for the reverse side pins under the LEDs and receiver. The side has a simple slot for the plug. If a taller wall size is used then the slot becomes a hole, with modest bridging that shouldn't require any supports. The retaining bar has a small edge inset to prevent pressue being applied to the board IC, and it is printed inset side up and needs to be turned over to fit the shell and hold the board snugly. The bar can be fixed with any M3 nuts/bolts. On the MaxMicron the mounting flange is a wide enough that it interferes with the heads or nuts of a fixing bolt, so a countersunk head bolt can be heat seated, gently, using a soldering iron and just enough heat and pressure to get the head to lie flush with the back of the shell. Then it is just a matter of mounting the sensor on the x-carriage flange.
