-=====Design=====
-The coupler is inspired by the one used for N scale.\\
-It can be used as active (servo) and passive coupler.\\
-The couple margin is about 10mm.\\
-Rolling stock can be lift up without struggling with hooks.\\

-====The Print====
-{{:robvrs:3d:coupler-set-printed.jpg?400}}\\
-Let cool down the bed to room temperature, and gently loose the spring.\\
-The other parts are not soo very sensitive.\\
-====Remove the support====
-Loosen the support with a tiny screwdriver, and push it out:\\
-{{:robvrs:3d:coupler-remove-support1.jpg?400}}\\
-{{:robvrs:3d:coupler-remove-support2.jpg?400}}\\
-{{:robvrs:3d:coupler-remove-support3.jpg?400}}\\
-====Drill====
-Use a 3mm metal drill, and clean up the support with a slow rotation speed: ((Avoid heat up the PLA.))\\
-{{:robvrs:3d:coupler-drill-chassis.jpg?400}}\\
-Drill only one side of the coupler; In the other side the M3 screw will be thread in.\\
-{{:robvrs:3d:coupler-drill-coupler.jpg?400}}\\
-====Rasp====
-Depending on the 3D print quality it could be needed to rasp very little to make rotation between chassis and coupler very easy.\\
-{{:robvrs:3d:coupler-rasp.jpg?400}}\\
-{{:robvrs:3d:coupler-rasp1.jpg?400}}\\
-====Connect Coupler with Chassis====
-The chassis and coupler can be connected with a M3 22mm threaded screw:\\
-{{:robvrs:3d:coupler-connect-chassis1.jpg?400}}\\
-{{:robvrs:3d:coupler-connect-chassis2.jpg?400}}\\
-Tighten the screw loosely so both parts can rotate easy:\\
-{{:robvrs:3d:coupler-connect-chassis3.jpg?400}}\\
-====Cut servo====
-Only a small edge must be cut off from the servo pad:\\
-{{:robvrs:3d:coupler-cut-servo1.jpg?400}}\\
-{{:robvrs:3d:coupler-cut-servo2.jpg?400}}\\
-====Put it all together====
-Adjust the servo position with the correct PWM before mounting the lever.\\
-Only the spring can get broken, but is printed new again within a few minutes.\\

-{{:robvrs:3d:coupler-assembled3.jpg?400}}\\
-{{:robvrs:3d:coupler-assembled.jpg?400}}\\
-====Passive Coupler====
-For a passive coupler, without servo, the spring must be 2mm longer as commented in the source:
-<code>
-// Drijfstang V1
-translate([0,30,0]) {
-  LENGTH=28; // 28 voor servo, 31 voor passief.
-</code>
-This spring connects to the coupler lever and the far most servo mount point.\\
