A fully parametric lock for cabinets with any knob or handle dimension!
Introduction
I did not see a model like it so when my cats kept getting into their food cabinet, and I got tired of using a rubber band for the knobs, I finally made this. This will certainly keep out any curious critters or children. I do not have any handled cabinets to test this on but I believe you can adapt it to fit inside of a set of handles to keep them secured as well. I hope you find it helpful and can make it fit your usecase!
The included gcode and stl are for reference only - They were designed for my cabinet specifially so unless you want to mess with the scale percentages in your slicer, I HIGHLY suggest you download the .scad (OpenSCAD) file and follow the directions below. A set of digital calipers will make taking your measurements much easier.
TLDR: Measure things out, adjust the parameters in OpenSCAD, test print if you want, print, ???, profit.
Print settings
Infill: 10-25% 3D Honeycomb; I did mine at 25% so that it would be fairly strong and not break if a pet or child tried to force it
Layer Height: 0.3mm; pick
Perimeters: 3
Solid layers Top & Bottom: 4
Material: PETG is ideal, but PLA or anything will likely suffice
How to customize your own! (Pictures included above)
- Measurements
- holeDistance - The distance between the inside of your knobs/handles
- holeDiameter - The diameter/length of the knob/handle where the lock will be resting
- partDepth - The depth of the back of the knob/handle to the wall. This will be the overall thickness of the part
- Others - Estimate the width and height that you want it to be. Be sure there is enough structure to keep it strong above the cutouts.
- OpenSCAD - Open .scad file and enter the measurements that you took. On the right there is a “Customizer” pane where you can do so. Adjust the height and width to your liking. Next press F6 to render and then F7 to export your model to an .stl
- PrusaSlicer (or whatever slicer you use)
- I suggest you first print a 2 or 3 layer part by setting the “z size” to .5 mm or less to make sure the measurements you took were accurate and translated properly.
- Whether you choose to do a test print or not you are ready to print the real one. Use the suggested print setting above or use your own
