3D Models Collection

Overview

This repository gathers a set of parametric OpenSCAD designs for everyday 3D prints. The models range from cable organizers and modular wall storage to planters, hobby parts, and small household accessories. Each .scad file can be opened in OpenSCAD to customize dimensions before exporting printable meshes (.stl/.3mf).

You can see models visualisations here.

Repository layout

• openscad/ – source models grouped by theme. Most folders also contain pre-exported meshes ready for slicing.
• openscad/cable_organizer/ – reusable cable spool core (spull_complete.scad) and preset variants for thicker wires and watch chargers.
• openscad/honeycomb/ – modular hexagonal wall system with clips, panels, perimeters, and corner pieces.
• Other .scad files in openscad/ are standalone household, hobby, or plant-care prints.

Working with the models

1. Open a .scad file in OpenSCAD.
2. Review the parameters defined near the top of the file and adjust dimensions to fit your hardware or use-case.
3. Render (F6) to create a solid mesh, then export it as .stl or .3mf for slicing.
4. Several designs expose booleans (for example showTopPart, showCenter, showBottomPart) that let you print assemblies in separate pieces. Toggle them as needed before export.【F:openscad/cable_organizer/spull_complete.scad†L108-L136】【F:openscad/cable_organizer/spull_bigger_thin.scad†L1-L18】

Model catalog

Cable management spools (openscad/cable_organizer)

• spull_complete.scad – Core generator that builds a two-part spool with a customizable wire channel, hook ring, and optional large cut-outs for gripping or cable exits. Key parameters let you set the inner/outer diameters, spool height, wire diameter, hook geometry, and whether to render the top, core, or bottom bodies for separate printing.【F:openscad/cable_organizer/spull_complete.scad†L1-L149】【F:openscad/cable_organizer/spull_complete.scad†L200-L253】
• spull_bigger_thin.scad – Uses the core generator to produce a taller 70 mm body with 4.5 mm wire channels and exposes only the center section (ideal for remixing with other end caps).【F:openscad/cable_organizer/spull_bigger_thin.scad†L1-L18】
• spull_watch_charger.scad – Variant sized for round smartwatch chargers: expands the inner diameter to ~39.5 mm, outer diameter to 45 mm, and shifts the wire channel upward to accommodate the puck form factor.【F:openscad/cable_organizer/spull_watch_charger.scad†L1-L23】
• spull_simple.scad – Simplified body that replaces the sculpted shell with a slimmer form, adds posts for wrapping cable ends, and still accepts the same adjustable spool core.【F:openscad/cable_organizer/spull_simple.scad†L1-L132】【F:openscad/cable_organizer/spull_simple.scad†L200-L237】

Modular honeycomb wall system (openscad/honeycomb)

• honeycomb_element.scad – Defines the base hexagonal cell with configurable clips and locking pins on each of the six faces. Booleans (pin_1…pin_6, slot_1…slot_6) let you create tiles that interlock on specific sides.【F:openscad/honeycomb/honeycomb_element.scad†L1-L116】
• panel_9x9.scad – Builds a 9×9 array of cells, automatically mixing clip and pin configurations for edges and corners so large panels stay aligned when assembled.【F:openscad/honeycomb/panel_9x9.scad†L1-L29】
• Perimeter and corner pieces – Files such as perimeter_top_double.scad, perimeter_bottom_single_v2.scad, and corner_7.scad trim cells to create tidy borders, corners, or side caps when mounting panels to a wall.【F:openscad/honeycomb/corner_7.scad†L1-L49】【F:openscad/honeycomb/wall.scad†L1-L132】
• wall.scad – Example assembly that positions multiple panels plus perimeters and corners to form a full wall layout, useful as a reference when arranging your own configurations.【F:openscad/honeycomb/wall.scad†L1-L154】

Plant care and bottle accessories

• watering_box.scad – Square self-watering planter base with a recessed pot seat, central drain/fill tube, and optional side tube for irrigation lines.【F:openscad/watering_box.scad†L1-L31】
• watering_box_round.scad – Round variant with similar reservoir geometry and optional radial supports for additional rigidity.【F:openscad/watering_box_round.scad†L1-L37】【F:openscad/watering_box_round.scad†L39-L48】
• watering_box_round_with_device.scad – Adds a pocket for electronics (e.g., pump or sensors) plus a routed cable tube, enabling automated watering setups.【F:openscad/watering_box_round_with_device.scad†L1-L48】【F:openscad/watering_box_round_with_device.scad†L50-L60】
• bottle_cap.scad – Rounded cup-style cap sized for ~39 mm bottles, with six internal gripping arms and three external legs so the bottle can be suspended or drained upside down.【F:openscad/bottle_cap.scad†L1-L92】

Household utilities and workspace helpers

• battery_plug.scad – Simple 18 mm diameter plug with four 1.5 mm pass-through holes for organizing small cylindrical batteries or covering exposed terminals.【F:openscad/battery_plug.scad†L1-L18】
• hook_big.scad – Large flat-backed hook created via a tapered extrusion, useful for hanging bags or headphones from shelves or wall mounts.【F:openscad/hook_big.scad†L1-L22】
• pen_monitor_holder.scad – Clip that slides over a monitor bezel and provides a rounded 35×45×55 mm pocket to park pens or styluses within reach.【F:openscad/pen_monitor_holder.scad†L1-L48】
• trolley_coin.scad – Shopping-cart coin replacements in two styles: a Euro-sized token and a handled version with “NeuConf” lettering for easier retrieval.【F:openscad/trolley_coin.scad†L1-L53】【F:openscad/trolley_coin.scad†L55-L72】

Kitchen, hobbies, and props

• cake_mold.scad – Thin-walled hemispherical mold (80 mm radius) with a flat base for casting or baking dome-shaped desserts.【F:openscad/cake_mold.scad†L1-L16】
• spinning_top.scad – Gyroscopic top with a faceted core and three magnet pockets for tuning spin stability.【F:openscad/spinning_top.scad†L1-L52】
• lightsaber.scad – Removes a cylindrical channel from the included emitter shroud STL, tailoring the prop to house electronics or a blade stub.【F:openscad/lightsaber.scad†L1-L12】

Electronics and optics

• cherry_mx_v2.scad – Parametric Cherry MX keycap featuring a gently spherical top and cross-shaped stem; adjust cap_size, cap_height, and inner_size to fit different switches.【F:openscad/cherry_mx_v2.scad†L1-L32】
• linseHolder.scad – Lens holder with a ball-and-socket connector system. Modules generate both the lens cup (with space for a 59.75 mm optic) and a matching connector element with tensioning cuts for snap-fit articulation.【F:openscad/linseHolder.scad†L1-L78】【F:openscad/linseHolder.scad†L80-L142】

Printing notes

• Most designs set $fn to high values for smoother curves; you can reduce these for faster previews or increase them for finer prints.【F:openscad/bottle_cap.scad†L1-L3】【F:openscad/watering_box_round.scad†L1-L8】
• Several folders include pre-exported .stl and .3mf files if you prefer to slice without modifying the source. The OpenSCAD files remain the single source of truth for making dimensional tweaks.

Contributing

Feel free to extend existing models or add new ones. When contributing:

• Keep parametric variables grouped near the top of each file for easier customization.
• Include rendered previews (.stl/.3mf) when possible so others can quickly print without rebuilding the mesh.
