I know there are so many of these but mine works for the newer R2-D2 body.
About this creation
This one took me about 10 minutes to figure out and 5 to build. I also used the roof tile slant with no stud piece like most people.Well I used this criss cross piece with the stud at one end to make the third leg.I cut the criss cross piece with a dog nail cutter but you can use scissors, saw, etc. You put the cris cross piece in the R2 body and then the roof slant piece.Another R2's leg but, this one works for the newer R2 body
