So I increased the stand so it will support the buddy board case too.</p><p>I also noticed the stepper drivers on the buddy board get pretty hot, ok I'm sure they tested the thermal limited BUT electronics don't like to be hot in the first place... So...</p><p>During the design of the Z-Bottom Stand, I noticed there was room for those small heatsinks! so I made square holes in the buddy board casing and... now you got something cool!</p><p>The bigger stand that supports the Z-Bottom has a channel for the LCD ribbon cable.</p><p><strong>Hardware Needed:</strong></p><p><i>4x Heatsinks Size: 0.9×0.9×1.2cm/0.35×0.35×0.47in</i><br><i>5x M4x16 Hex Bolts</i><br><i>5x M4 T-Nuts for 3030 profiles</i><br><i>** 5x M4 Square Nuts / Block Square Nuts (if you don't have T-Nuts)</i></p><p>If you do not have M4 stuff...
