I needed a tray of compartments to put screws in when taking laptops apart and the like so I printed one. I designed it with a noddy little OpenSCAD script so I can make one with long and thin compartments for airbrush needles or whatever.

I'll probably update this at some point to allow different thickness walls between compartments and for the outer walls and maybe for rounded bottom compartments.


The variables in the .scad file should be fairly self explanatory, compx and compy are the size of each compartment in mm; wall is the wall thickness (again in mm); nox and noy are the number of compartments in x and y and deep is the depth of each compartment.

Isn't it cheaper to buy these lol

I love this design. You can make a tight-fitting lid by adding up the values (including the spacers, and use that for the dimensions of the lid. It fits tight and "locks" because of the ridges of the layers.

In my second picture I show a cover I made for the 5 X 2 tray. I used Openscad to modify the original file for my tray. I modified the original tray file so the cover is slightly larger than the tray, it has one compartment and the sides are a little less than the height of the tray it covers. I'll use an elastic to hold the cover on.

This project will give you an excuse to rummage around in the .scad file.


Can you please share the lid file??

Thanks 8-)

I would be happy to do this but I'm not sure how to give it to you.

Understand I'm not good at Openscad. What I did was to open my 5 X 2 file in Openscad and at this point you can see the criteria that was used for the compartments. I fiddeled until I got one large compartment. I then added 4mm (Y axis) and 5mm to the (X axis). It took two prints to get to the poi
nt where the cover goes on snugly.

If you you don't have Openscad download it and give it a try. IN my opinion it is not a great program for some like me who doesn't do much programming but it worked for this application.

Use this project to explore new areas.

Nice On the Parametric!

My 5 X 2 tray printed perfect on my TOM.

This will come in handy.

Great stuff, thanks.. I needed some more storage trays. This will save me heaps of cash.
