I see all the complicated design on web about dry box,honesty to say, I do not like them,My idea is to use the silicon dry box ,base on it add a arm for bearing,glue the locker in the box,use the simples way to solve make hole,screws troubles things,just use glue ,keep the box sealed

  1. you must use 100%filling in 0.4nz PLA or petg like to print it,becos the arm need firm enough for bearing,

  2.the locker size can be adjusted in the prusa sicer base on your box width .

 3. I just add the arm in prusalicer , so you need use this software to print it,

  4.the ring is the final locker when you put the bearing int he locker, You also do not add it. it just denpend on you. I desiged the locker have the tighing function .

  Have a nice enjoy printing your daget.
