No-crash remix of the BZB coupler, this STL replaces BZB-1 from https://www.thingiverse.com/thing:2337507 by RamKat
The idea is to prevent the Z rod(s) from pushing the X-carriage and the nozzle against the bed, as with the usual Oldham system.
I've just opened the holes and extended the vertical walls close to them.
You might need to file the vertical slits a bit in order to let it disengage freely.
** NEW : ** Now with and adjustable version, as the original was 3.5mm too far from the chassis, this one will let you perftectly align your leadscrews
** Also new : ** Wider slit version will disengage more easily, no need for post print.
