Small canister box rack

This is a rack for 5 or 10 boxes of small canisters. The dimensions of the box is 160 x 135 x 35 mm, there are 30 small canisters in the box. These boxes can be bought quite cheaply online.

For a rack that holds 5 print Small canisters box rack B, for one that holds 10 glue B on top of A (PVA works really well). I print these in PLA without supports with the back flat to the bed. But the uppermost curve on the sides could benefit from a painted in support in the very centre of the curve.
