Case and lid for Tinkerkit T010010 Relay Module

thingiverse

This is a custom version of my standard case upgrade tailored to Davidmpye's standard case (box and lid). The custom case is sized to fit the Tinkerkit Relay Module, item number T010010. Based on my available mounting space, I had to keep the case compact. The basic box dimensions are 45mm x 55mm x 28mm. Holes for the lid mounting are designed to use #4 1/4-inch pan head screws. Mounting flanges added to the 45mm sides are also sized for #4 screws. The mounting holes on the Tinkerkit relay module are small, so internal board mounting standoffs are designed to work with #3-48 1/4-inch flat head screws. Flat head screws are used here because they reduce the length of standoff required under the board. A simple round hole is provided for routing wires to the relay output terminals. A simple notch is also available for signal, ground, and power wires if you're using the large interlocking connector for the board connection. This design is flexible and can be tailored through various parameters in the openSCAD file. Like Davidmpye's standard case designs this one uses roundedCornerCube.scad and nophead's polyhole.scad. The Rev A files reflect an update to my generic case improvement found at http://www.thingiverse.com/thing:643264. Those updates were mainly about labeling parameters, paths to the roundedCornerCase and polyhole files, and general file organization. It is no longer necessary to get the polyhole file since it's already part of the openSCAD MCAD library. The Tinkerkit Relay Module provides a 10-amp relay with NO-C-NC connections. The relay operates on 5V power and signal from an Arduino or similar processor. The relay input is buffered, requiring minimal current to control it. Instructions: Print the STL file if the 45x55x28 box suits your needs. To tailor it, download the roundedCornerCase.scad file from http://www.thingiverse.com/thing:8812. Download the Tinkerkit_relay_case.scad file and change the line with the correct path location for the roundedCornerCase file if you don't use the CUSTOM library folder. Locate and modify the parameters that require changes, then render and generate a new STL file.
