Use those Benchies

I took the Iron Throne Benchy into Tinkercad, created 5mm cutout in roof which on already printed Benchies you can drill, insert an led light in each cabin and either glue or tie in place.

Storage of all your printer waste Benchies now solved, hide them with your Xmas Decorations.

Whole process took less than 30 minutes with print, it's daylight & used a red led and a battery to demo so picture not best. Multiple colours and RGB LED's they look great hanging on walls windows or trees, being a grumpy old man I don't do Xmas, provided a bucket full of drilled benchies to grandchildren with battery operated lights to assemble.

TIP: Keeping them quiet for hours!
