The magnets which were included with the original design of the motorized mirror cover assembly have insufficient strength to hold the assembly together. Additional latches were added to the design to perform this function. An updated parts list and DWF model are posted (in both cases, the main parts list and model have not been modified–look for the updated file for this specific assembly). The threaded holes necessary to use these should already be present in the custom cover pieces that were received. Note that the long #10-24 screw/washers/nut shown replaces a standard #10-24 screw which was used to fix the Big detection lens holder to the main optical table. The washers/nut allow the screw to be fixed in position and still support the Big detection lens holder, while also extending out to be used to support the motorized mirror cover assembly. The custom 3d printed latch may have already been sent out to each lab that participated in the 2p-RAM workshop (if not, then please email or comment). For the side latches, it may work easier if they are inverted from what is shown, with the small, button strikes on the top cover piece. In the way shown, when the bottom cover is removed, the latches swing down into the assembly, potentially touching the dichoic/mirror, and generally getting in the way.
