How to tape something to the bottom of a brick I'm installing lights in my buildings (I'm using Neopixel strips, which have a flat back), and I'm trying to tape the lights to the ceiling. Of course, bricks and plates aren't smooth on the bottom, so double sided tape isn't working out too well.

Can you recommend either:


A plate or similar part with a smooth bottom (I'm familiar with the 2x2 round plate that has a rounded bottom, but I can't think of anything flat)
An alternate method of affixing small parts to the bottom of bricks and plates
Take a look at 11203 - Tile, Modified 2 x 2 Inverted. Works like your 2x2 round plate but is flat at the bottom.
