Cable Chain Anchor for the ERC TimSav Needle Cutter

thingiverse

UPDATED 04APR20. Added version 3 to the files. V.3 updates include: 1. The anchor is now longer, making it easier to mount the CNC Shield to the Arduino Uno after mounting the Arduino Uno to the side plate. 2. The back plate that goes against the ERC TimSav side plate is now 6mm thick. This allows users to use a 6mm spacer between the TimSav side plate and the Arduino Uno board, keeping everything on the same plane. 3. The hole in the link is bigger, allowing wiring to pass through with ease. 4. Pin recesses are deeper and taller, providing better clearance. V.2 Updates include: 1. A better link piece was designed to attach to other cable chain links. The original part had an elongated pivot button (male piece) that did not match with the pivot hole (female piece) on partner links. 2. Pin recesses were aligned and deepened a little, allowing variance in Arduino board pin depth. 3. A recess was added in the hole coming through the link to allow wires easier passage. 4. A gusset was added to the side for strength. Although it may not be needed, it can't hurt. 5. A hole was added in the above gusset to allow wire passage. This anchor is used to secure the cable chain to the Arduino mount board. Most folks assembling the ERC TimSav using a cable chain for wire management have simply left the end closest to the Arduino boards unsecured. Leaving it unattached or unsecured allows the cable chain to move with the Y-axis (especially if your links fit a little tight) and will cause stress on the wires and plug attachments on the CNC shield. This alleviates that problem. This anchor is a concept, and has not been printed or tested yet. It is based on the cable chain designed by Ryan Millikin (https://www.thingiverse.com/thing:3996883?fbclid=IwAR3I9O4N05oJxd1bTmvu4YOPYDptBUVs6xzZ-wQRy6oWR59BlGnJpOzmPAI) NOTE: There are many parts pictured, the only file for this thing is the anchor itself. The pics are just to show how it fits into the parts stack. This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/fGr3jmMSeaM
