Chain based Heat Bed Cable Guiding System for SnapMaker A350/A250

thingiverse

I redesigned the cable guiding chain for A350 heat bed for 3 reasons: 1) this is a low-profile version. The chamber is located below the heat bed, preventing the collision from the tool head (yes it happened to me); 2) the chain will not influence the y-axis. The existing version that the chain is moving toward horizontal sometimes hits the heat bed when the y-axis is moving; 3) this doesn’t require rewiring the cable. A standard printing setup will do. You may need support when printing the heat bed connector holder. This is a work-in-progress. The other axes will be included in the future. Appreciate any comment. UPDATE 1: I decided to change the direction of the cable chain. In addition, I redesign the whole thing so that the number of parts will be reduced. Now the spring for each link is no longer needed. UPDATE 2: Per request, I make a connector for A250. It is still at the development stage. UPDATE 3: Per request, the ``vertical design'' is uploaded.
