There are three parts that require glueing together. Place the handle in the main slot and glue on the back piece.
This was printed for a 4 year old to reach pretty high light switches and it's worked very well. It held up for 6 months with a 30% infill then snapping on the handle, I'd suggest printing the handle at 100% fill for strength.
Just a heads up the only way to use the light switch will be with the extension, adults included.
The author marked this model as their own original creation.
