Lack Leg Joiner

Just a simple way to stack Ikea lack tables by joining the legs. This is a 4mm thick square tube with a 4mm lip in the middle. Print 4 of them and stack one table on top of an upside down table if that makes sense.
I did two versions, a lack_leg_joiner_short is the shorter quicker version but not quite as tight, each end is 26mm. lack_leg_joiner_tall is 52mm on each end and makes the joint somewhat more ridged
