About this 3D model

Added an update that has a flange and nut slot. This version can use a hex head bolt and a wing nut. So, no tools needed to loosed or tighten. We've had a few Z-couplers break during shipment so we made these clamps that hold the x-axis from moving. This file is actually just the new bar clamp from the Prusa iteration 2 with one hole made smaller for an M4 screw. Simple part for a simple job. Hardware: x1 - M4 30mm SHCS x2 - M4 washer x1 - M4 nut
