wire shelf spool holder v2

the much loved wire shelf spool mount for ender 3 style spool holder redone to work better

this is forked from my og model here:https://www.printables.com/model/910699-spool-holder-for-wire-shelf

now it has walls on the side to prevent the spool holder from twisting and letting the spool fall off!



I just learned that there is nothing preventing the spool holder from fallling out beside the printer on top this is going to be fixed in a later version! but you can prolly just use zippy ties (lol)
