<p>Why?</p><p>I upgraded my VCore 3.0 to 3.1 parts, including the Oldham coupled bed arms, and I couldn't find a rear bed arm dragchain mount that fitted the new arms, combined with the “old” rear panel with the cable canal on the bottom so I designed my own (I used the following 10x15 drag chain with openings <a href="https://a.aliexpress.com/_mNyWcQy">https://a.aliexpress.com/_mNyWcQy</a>)</p><p>Features:</p><ul><li>Upper mount is directly mounted with the original M3 screws used to mount the RatRig cable relief</li><li>Elongated cable relief with a third cable tie mount</li><li>Lower mount features an insertion mechanism that ensures the straightness of the ascending part of the chain</li><li>Upper and lower dragchain mounting points are vertically in line</li></ul><p>Requirements:</p><ul><li>Use stiff material and print settings, especially for the upper mount. PETG will flex to much.</li><li>Need a little amount of supports on the lower mount, unless you REALLY have mastered your bridge settings</li><li>Upper and lower mount are designed for M3x4,6x4 heat inserts, the chain can be mounted using M3x6 countersunk screws.</li><li>You have to drill two additional holes in your bottom panel to fix the lower mount using M5 cap head screws and the corresponding M5 T-nuts for 3030 extrusions.</li></ul><p>Hope you like it :-)</p>
