KYOSHO Calmato Wing Fixing Strip

Hi there,
i got an used RC Model ... a KYOSHO Calmato Trainer 40 ... It's pretty nice but the wing fixing screws were missing and i needed to get some from the local store. Due to the fact that the screw head was quite small i decided to print a support strip to disperse the force of the screws a bit better. I designed it for M4 screws.

Maybe somone else can use it, too
