minimal anti-backlash solution for solidoodle

This is my antibacklash solution for the early solidoodle 3 with wooden bed .
i just turned upside down those 2 wood part holding the nut , and super glued the nut to the wood part . I put longer m3 screws - 4mm . and 4 springs that i`ve bought from Aliexpress to push the whole wood assembly upwards .
At first glance it seems to work .


the thing at download is a holder that might work better . i did not create the nutholder
