Customisable Mini Storage Drawers

This is a modification of my exisiting storage drawers. It has lost the ability to change the number of columns but does now have 2 extra drawer widths - double and quad!
.
This allows for larger items to be stored without compromising my original idea of small storage drawers.
.

The drawer sizes are:
Half Bin : 25 x 10.5 x 65
Bin : 25 x 24 x 65
Double Bin : 55 x 24 x 65
Quad Bin : 115 x 24 x 65
.
UPDATE 1: Small update to rotate the rack ready for printing.
.
UPDATE 2: Added new drawers with vertical handles, as suggested by ronthomp.
.
UPDATE 3: Added the sizes of the draws in description.

Sorry for all the fullstops but I can't seem to get blank lines in my text anymore.
