To increase the rigidity of the LumenPnP (v3) toolhead, I decided to modify Stargirl's excellent linear rail mod (https://www.printables.com/model/278803-lumenpnp-linear-rail-mods-v3) to support dual linear rails for the x-axis. This allows me to place 0402s more accurately.
Although the situation was improved by switching from v-slot rollers to a single linear rail, the toolhead was still able to flex a little, affecting accuracy in the y-axis. The v3 cable chain, especially, would cause the toolhead to twist a little.
The x-gantry-block-mount was modified from Stargirl's linear rail mod to be a bit stronger, and to be a closer fit for M5 nuts (they were a bit loose). The x-gantry-back part was modified from the LumenPnP part.
