This is a Gridfinity paint rack for 27mm round paint bottles (like Master Series Paints) with a pull-up handle to pull the rack out of a drawer easily. Top, bottom, handle and handle stops print separately. Suggest using CA glue (2 part, liquid and spray) to adhere the components together. I printed the handle on a SLA printer, but it should also print fine on a FDM (perhaps with a raft). 

Insert the handle into the top piece, then glue on the handle stops. Next, glue the top onto the bottom with glue on the bottom of each of the vertical cylinders. The vertical support cylinders double as paint brush holders!
