Saw many different light switch plates that were building brick like (unnamed brand) out there. However, I seemed to always have issues with printing and certain blocks (not to be named) would not stick, you couldn't get it on or off properly. I did mine in PLA, but you can do PETG for a little more durability with lasting. Been using them over a year, but the kids don't take Lbricks on and off constantly, so far so good on durability.

Added the double decorative switch plate for those that need it.

.16 layer height

ironing on - I use 15% at 30mm

Supports - I used Default Snug supports.

UPDATE: 5/29/24 - Added the Triple and Jumbo plates that were requested. Please test them out and let me know if there is an issue with them I can adjust. I don't have any Triple switches in my house so measurements were best I could do off a standard plate.
