Ender 3 S1 quad Z-brace mod

thingiverse

Reduce wobble by securing the Z axis frame of your Ender 3 S1 to its base. Creality made the non-Pro version really difficult to attach stuff to the corners, so let's do it anyway! The front brackets bolt over the existing front cover. There are no screw holes near the rear corner brackets, so instead a fifth threaded rod runs horizontally to hold them in place. Parts required: - M4 threaded rod cut into 500mm x4, 360mm x1 (2.36 m total) - M4 nuts x20 - M5x10mm screws x2 (top) - M5x25mm screws x4 (front) Tools required: - Hacksaw or oscillating tool, for cutting the rods - Various wrenches/drivers for the screws and nuts - 7 inch carpenter square (optional) The M5x10 screws should have an 8.5mm hex socket head, like the ones holding the frame together. The M5x25 screws can have any head shape, as long as the back is flat. While assembling, pluck the threaded rods like a guitar and listen to compare tension. Raise the head to Z=250 so you can fit the carpenter square beneath it. When you're happy with the positioning, jam pairs of nuts together to lock them in place. PrusaSlicer settings: - 0.2mm layer height - 5 perimeters (enough to fill in around the rods) - External perimeters first (better dimensional accuracy) - 20% gyroid infill - Supports: - Style: organic/tree - Top/Bottom contact Z distance: 0.2 (one layer height) - Top interface layers: 3 (heavy)
