I designed a little shim for holding the nut traps in place against the acrylic. I believe they are a nice and clean solution instead of using tape to hold them in place as suggested in the wiki. They are removable after the nut trap is secured or they can be left there if they are hard or impossible to reach like in the supports between the floor panels. Make sure the nuts are fitted flush into the nut traps like this: Then you can fit the shim to hold the nut trap like this: Maybe E3D can include a bag of these little things to make the future kits a little easier to build. Here is the STL file if anybody wants to print them.
