BROR Enclosure V2

UPDATE Shelf support holder
I added optional holder brackets for the two additional support beams (see instruction pdf page 1). Those can be used when the supports are not held securily by simply quenching them into the frame. If used, print 8 copies of it, add a M3x5mmx4mm heat insert into each of those into the exterior side of the screw hole and install an M3x8mm hex screw flush into each bracket. Insert the bracket in the frame to sit flush with the support beam and then lock it in place by tensioning the screw as much as needed. Add a bracket to both sides of the support beam at the front and at the back. 


UPDATE V2
I modified the pillars so that they are now modular. The original design was for an enclosure 3 levels high. With the updated version the height is modular, with a minimum of 2 levels. For every additional level you can add one more “mid”-pillar piece in between the “bottom” and “top” pillar piece. The pillars are also compatible with the wider BROR shelf. 

The supplied dxf files are still designed for the standard height of 3 levlels. If you choose a different dimension for your BROR enclosure please adjust the panel cuts accordingly. You will also need a custom cut backplate or an adapter plate in combination with the upright shelf floor. If you want to build the standard size, the instruction guideline from V1 still applies.  

The original version V1 files are still attached in an zip file.
