This is an OLED mount for a nerf Styrfe. It fills in the back half of the jamdoor section, so I have included a replacement jamdoor that is shorter than the original.
There is space for two 6mm square pushbuttons that have buttons less than 2 mm tall. The OLED is held in front by two tiny screws, and an m3x6 bolt in the back can be used to hold up the OLED's rear section. A nut can be used on the OLED to protect it from the m3 bolt.
