Telescoping back scratcher (print in place)

thingiverse

Update: There is now a v2 which is a few inches longer a bit sturdier. There is also a third version that's even longer, but I have not test printed it. Some people have had problems with the bottom layers fusing together. It may be necessary to adjust your slicer settings to compensate for elephant's footing. The inner layers are quite thin so don't be too rough when expanding and contracting it. It's best to cover the bottom opening when collapsing it. Print it vertically. At least 50% infill is recommended No need for supports.
