Construction Brick Membrane Keycap (clearly not LEGO)
thingiverse
With all the attention gained by mechanical keyboards and all the cool keycaps you can get for them, us poor membrane guys are left sad and lonely. But fear not, I have designed this little handsome thing so we can all join the cool kids club. The keyboard I used as a reference is an el cheapo Trust model. The keycap shaft is about 6.9 x 6.9mm, make sure it fits your own model. Pics of the original caps are attached for reference. The actual brick should be fully compatible with LEGO pieces, should you desire doing something fancy with it.
