Lemax Street lamp Stand

Tried a similar print from another site but the hole was too large and the lamp still had a tendency to tilt. I struggle without a good Step file to make changes so made my own.

I have attached 3 different inner circle sizes. Just incase subtle changes in printing leave your lamps a leaning. 18.8mm was the best fit for me  

18.8mm,  18.9mm and 19mm.  

I made no changes to the easy slicer and no supports needed  

There is a step file and 3mf 19mm
