MP Select Mini X-axis Gantry, no rod cut

thingiverse

I've noticed that these supports are often published without a clear explanation of their purpose. Some people refer to them as Z support, but they have no effect on Z movement whatsoever. X support is another common name, and I used it myself, but it doesn't affect X movement either. In reality, the Y axis is what gets stabilized. A cantilever beam isn't a very stable structure, and the free end can move around freely. If you feel the end of the X-axis beam during printing, you'll definitely notice it moving. So, let's take a closer look at the X-axis support. I started with the X-axis gantry by 70-77, which features dual top rods that make the support extremely stiff and provides mounts for other accessories. It also has the kind of over-engineering that I really like. I ended up using about half of the parts and made only one change: adding bosses for set screws to secure the rods. To mount the gantry_d slide, I drilled and tapped the X-Axis end cap for M3 cap screws. Then, I used hot glue to attach the bearing. For the base of the vertical support rod, I took a different approach. I liked the adjustability of 1cheeseball1's mount and modified it to use the 8mm rods that 70-77's design calls for. I incorporated the mount into a side panel that included the no-drill bed rewire feature. As an added bonus, if you use 8mm x 300mm rods, you won't need to cut them at all. If you want a base that mounts on top of your existing side plate instead of replacing it, just use the base in 1cheeseball1's original design. The side panel is a bit large, but it should print fine on a Select Mini as long as you don't attach anything to it. Here are the parts you'll need: * 3 x 8mm x 300mm linear rail rods * 1 LM8LUU Linear Bushing * 3 M3 x 10 cap screws for locking Y axis adjustment and mounting gantry_d slider * 4 set screws (I used #6 Imperial) * 4 M3 x 20 cap screws * 4 M3 nuts * 8 M3 flat washers
