Spine for rod motor mount

thingiverse

This is a spine segment for our rod motor mount (https://www.thingiverse.com/thing:3574454) that makes the wood, aluminum or carbon rod removable from your model unless you want to glue it in place permanently. To make this work, print as many segments as needed (3-5 is usually sufficient for most models), then slip them onto your square 1cm rod and space them evenly apart. Mark where they should fit on your model and carefully dig out the necessary channels before gluing these spine segments into their final positions. Each spine features a small hole that serves as a security pinhole, which you'll use to lock the rod in place by drilling through it with a screw, toothpick or other thin object that fits perfectly through both the spine and the rod. Do not glue this pin - it's what allows you to remove the rod if needed later on. For reference, check out the photo of how this setup looks. These spines print without any support required and are incredibly lightweight. The flaps on either side should be glued into your model's body, where they'll grip securely. They can withstand crashes from standard motors up to 70 grams in weight and 1kw of power. This is the lightweight version of this mount; for heavier motors, use our tunnel instead (https://www.thingiverse.com/thing:3580173). To print these spines effectively, use 20% infill or more and set your printer to print with three layers on each wall and bottom layer. After printing, make sure to sand all surfaces that will be in contact with glue using 100 grit sandpaper and then clean them thoroughly with alcohol to ensure the best bonding results possible.
