Thank you for this design! It's seriously underrated and should be more popular. There's not a lot of printable MCM designs available. I printed mine in PETG and it came out very well. I used 3 perimeter layers instead of 4. I also designed my own lamp socket adapter in Fusion 360 to work with the common 40mm E26 sockets from Aliexpress. You can have this file to include in your design if you want.
