BMCU enclosure bracket with four-tube fixture and large-angle three-way connector

To complement the enclosure, I fabricated a BMCU suspension bracket, a four-spool holder, and a three-way connector at an optimal angle, facilitating the use of external suspended spools for printing flexible materials.

The spool rack utilizes a passive rabbit-style rewind mechanism, secured with a 1020 profile extrusion assembly. For this, I designed lateral fastening strips to join the extrusions. Simultaneously, I created number plates fastened to the extrusions using screws and boat-shaped nuts.

The four-spool holder mounts to the factory buffer position. The rectangular design allows spools to pass directly through (suitable for sufficiently long spools), while the buffer-style design uses two short spools inserted and secured on either side (suitable for shorter spools). Alternatively, one could incorporate a nozzle diameter compensation during printing to allow spools to pass directly through (though I have not yet tested its feasibility).

Unable to locate a three-way connector at the required angle, I designed my own, maintaining a similar bend radius to other spools.
