honeycomb-wall-scad

A parametric honeycomb storage wall in OpenSCAD, with the snap-in inserts, clips and attachments that go on it. Print the wall in panels to fit your bed, mount it with screws through screw-type inserts, and push inserts into any cell. The wall, the inserts and the clips all read one set of sizes, so changing the hole, the wall or the depth keeps every part fitting.

The parts

File	What it makes
hsw.scad	The shared sizes and the cell geometry. Every other part includes it.
honeycomb-wall.scad	The wall: fill a print bed, or lay it out column by column.
inserts.scad, examples/inserts.scad	Snap-in inserts, single or joined in groups.
hsw-clips/hsw_clip.scad	One-way clips and a connector that joins two wall panels. Needs BOSL2.
attachments/	A screw-on hook, a plier holder, and a tool rack of pegs or rings.

Shared sizes (hsw.scad)

Parameter	Default
hsw_hole	20	Hole across flats, mm.
hsw_wall	1.8	Wall around each hole; neighbouring cells sit wall to wall, 23.6 mm apart.
hsw_depth	8	Grid depth, back to front. At least hsw_lock_z + hsw_lip_depth (7.1 mm).
hsw_lock_z, hsw_lip_depth, hsw_lip	5.1, 2, 1	The hole is hsw_hole wide from the back to hsw_lock_z, then widens by hsw_lip per side to the front opening, hsw_lip_depth deep.
hsw_back_chamfer_w, _h	0.4, 0.5	Chamfer on each hole’s back edge, against elephant’s foot.

Set them with -D on the command line, or in the Customizer of whichever part you’re making.

The wall

Open honeycomb-wall.scad. By default it fills max_grid_width × max_grid_height: 211 × 248 mm, about 10 × 10 cells on a Bambu Lab A1.

• column_data_index picks a column-by-column layout from column_data, such as the example above or the two layouts for the ends of an IKEA 365+ drybox.
• include_offsets moves columns up or down by whole cells, include_gaps leaves chosen cells out, and include_solids closes the front of chosen cells.
• edge_left, edge_top, edge_right and edge_bottom cut the outer cells in half and close them with a flat wall, for butting panels together or against a frame.

Print it back face down.

Inserts

An insert’s body pushes into a cell, its lip stays on the front face, and six snaps hold it. In examples/inserts.scad, pick a preset, or set it to "custom" and set layout to a list of rows, bottom row first, each a list of types:

Type	Centre
0	no insert
1	open
2	solid
3	countersunk screw
4, 5, 6	M3, M4, M5 nut trap
7, 8	screw hole with an open back, plain or countersunk

Rows are half a cell apart and odd rows sit half a column to the right, so a layout interlocks like the wall’s cells. Neighbouring inserts are joined by connectors across the wall between them. tolerance shrinks the parts that go into the cell, and decoration adds a groove pattern and chamfers to the face. Print inserts lip face down.

Clips and attachments

hsw-clips/hsw_clip.scad makes a one-way clip, with an optional hex or rectangular base, and a connector that holds two neighbouring wall panels together. It draws a clip by default (generate_clip); turn on generate_clipconnector for the connector, and a base if you want one.

The attachments screw to the wall or anywhere else:

• attachments/hook.scad: a J-shaped hook, filleted or chamfered, with optional countersunk screw holes.
• attachments/plier_holder.scad: a rounded wedge for pliers, screwed on through its middle.
• attachments/tool_holder.scad: a flange strip with a row of angled hex pegs (bored through, for bits or spokes) or rings for screwdriver shanks.

Checks

just test takes about 2 s on OpenSCAD 2026.10.15. It checks:

• the wall’s size, its pieces and its volume, for a full bed, a custom layout, all four flat edges, and a 25 mm hole with a 2.5 mm wall;
• the hole’s width at four heights: the back chamfer, the straight part, the widening and the front opening;
• an insert seated in a cell, at the default and the 25 mm sizes: the lip lies on the front face, the body clears the hole, and only the six snaps press into the wall, behind the lock;
• the clip at both hole sizes, insert layouts joined and apart and each preset, every attachment, and that a depth too shallow for the lock is refused.
