Fully parametric spice rack

This is a fully parametric spice rack, but also can be converted to a basic drawer system for pretty much anything else. The main goal was to have railed drawers with an endstop and have the structure be simple enough that it wouldn't take ages to print but it would still hold the weight of the top row.

The original design configuration was a 3x2 module with an extra column at double height that would accomodate the tallest spices. My main limitation was the print size, so I decided to split everything up in pieces. The trays are one piece, and if positioned in diagonal you can fit a 260mm (+10 of the handle) long tray on a Prusa i3 MK3. The structure is split in front structure and back structure and these are joined by T or L beams that are glued in. The width was 47mm, because I figured that 99% of my spice containers fit in that and it fit in the space I had for it. Likewise, 120mm if height seemed like a good compromise.

I've generated the following STL files (all for 260mm length, 47mm width and 120mm height):

• L beam
• T beam
• Tray
• An open 3x2 structure (A)
• An open 3x2+extra structure (B)
• A closed 3x2 structure (C)

These may be enough for your needs, but you can use the included OpenSCAD file to create your own to your dimensions.

##Parameters:

• To: Minimum print gap, mainly used for the rail
• Ts: Print gap for smooth movement (tray and structure)
• Tg: Print gap for two pieces that are to be glued together
• Tw: tray width
• Tl: tray length
• Th: tray height
• Wt: wall thickness, is added outside of the previous tray dimensions.
• Hw: handle width
• Hh: handle height
• Hd: handle depth
• Ht: handle distance to top
• Hx: handle thickness
• Sx: number of structure units in x
• Sy: number of structure units in y (technically in z, but these print horizontally)
• So: open (1) or closed (0) top most level
• Sb: number of open (no top) structures in addition to Sx x Sy, added to the right
• St: Structure thickness (2mm minimum recommended)
• Sd: Structure depth
• Ss: Slot depth, minimum should be 2mm; Adjust accordingly.
• Sh: Structure height

There are a couple of images as examples of what you can accomplish by modifying the parameters.
