If you are like me, when taking apart something you will often start to misplace small screws and such. But you also don't have a lot of space so having a full-size parts tray has always seemed like a bit of a waste. And also you wish it could be magnetic. I think that its just the 2 of us now, and have I got the printable for you!

This parts tray is parametric, meaning you can modify many things about it in the customizer or OpenSCAD. Change the width/height/depth, containers, beveling, magnet size, disabling magnets, tapered edges in the compartments, tolerances for the hinge, and more. If this seems like the kind of thing you might enjoy, hopefully I gave you enough settings to customize it to fit your need.

Note: With the magnets I used (6mmx3mm), it is strong enough to gently hold some screws right in the middle, but it wouldn't hang onto them if I bashed it to the ground.

I wanted to be able to attach a box of batteries to the back of my utility closet door, so I made a solution to this non-problem!

The box stores batteries at a 45 degree angle, so it can be used standing or laying down. It has many customization options. Choose what kinds of batteries, how many per row, how many rows, where the mounting brackets are, the padding between cells, etc. Handles AAA, AA, C, D, and 9V using the Customizer. I did NOT include support for flat cell batteries. As you may see I just jammed them in a 9v slot.

If you know a little OpenSCAD, you can easily add your own battery types with some light variable tweaks! Add storage compartments of any size using this method!

Fair warning, this is NOT efficient to print. My demo took 22 hours to print at 0.2 SPEED setting in Prusa slicer (all defaults). I'm sure with some setting fiddling you could knock it down, especially if you switch out a larger nozzle. Be careful lowering the infill too much though, those mounting tabs rely on it too! You don't want to go hang it up and have them go crunch. I used washers to help with that.
