# Cardboard for Project Enclosure Boxes?

One of the things this pandemic did to me and others is deny me access to Dallas Maker Space and killed/damaged a lot of my vendors for specific items. Enclosures in specific took a major hit. I could always 3D print a box or get one at Tanner's Electronics or Fry's Electronics (both went under and are gone now). My project (while not disposable) is something I don't think is major enough to spend any more money than I had to, I have started weaning myself from batteries where I can. So I salvaged a AAA batter box from a small flashlight I had destroyed modifying it to use a USB power cube. The only parts I spent money on were 3 resistors and a push button switch (total cost, well under $5). I have lots of cardboard from cereal boxes, etc so I made a project instead. I can test 1½V batteries w/ ½A. After checking a pile of batteries I now throw it into a storage box (don't need it anymore)... #### ElectricSpidey Joined Dec 2, 2017 1,525 I'm sorry but...that is just cheezy...

Splurge and pick up some$1.50 food latch lid containers from the $1 store they make simple project boxes, I am just in the process of the latest PWM generator, will post a picture when done.!! #### Danko Joined Nov 22, 2017 1,059 I have lots of cardboard from cereal boxes, etc Congratulations! so I made a project instead.

This being before I became a mod, the other mods were in on it. #### dl324 Joined Mar 30, 2015 12,668 I've been using copper clad board to make "boxes". A box for switches: I tacked corners with solder and taped the bottom on. A battery "box" with no sides: This was for one of my Daughter's science projects and I needed to prevent kids from being able to short the batteries. Partial box used to mount a PCB to a display board: Lately I've been thinking about using plexiglass, assuming I can cut it with my metal shear, and some UV cured glue. #### Yaakov Joined Jan 27, 2019 2,341 Lately I've been thinking about using plexiglass, assuming I can cut it with my metal shear, and some UV cured glue. You will have problems, cutting plexiglass with a shear, it will shatter on the edge, A table saw does and excellent job, though. As far as adhesive goes, there are acrylic specific adhesives that bond the plastic itself. Cheaper and stronger than UV glues. When I worked at the Museum of Science in Boston (1980s) I did a lot of plexiglass fabrication. I love working with it, it's great material. Here's something I made, one of my favorites: #### BobaMosfet Joined Jul 1, 2009 1,501 One of the things this pandemic did to me and others is deny me access to Dallas Maker Space and killed/damaged a lot of my vendors for specific items.

Reminds me of sheet-metal drafting when I was in that career (and architecture as well). Learned all kinds of ways to make tabs and cut-outs and so forth- plans for, that is- and could make all kinds of enclosures.

Check out Hammond for enclosures- they have a variety- many off the shelf that are easy to fit a small PCB and other things into for very little money. project enclosures.

I tried that but did not like the edge finish, after a little research i came across a few Youtube videos that show using the hook knife method, really nice and clean edge!

I have made a few acrylic enclosures over the years, but now I use expanded PVC.

That's a good method for glazing thickness sheet but for thicker stuff it won't work properly or at all. Edge finishing can be done different ways. Scraper, sanding, flaming—I prefer to spend the time to sand it creates invisible joints when done properly.

Scoring is good, though for thinner sheets.

Isn't that soft foam construction?

I might have seen that. Mid-90s my son used to go to the Saturday science camps that were held in the Museum. And the company I worked for was one of the museum’s sponsors, with their name on the large sponsor wall in the lobby. MIB, Inc.

MOS was one of my favorite ever jobs. I am seriously considering building a few science exhibits as soon as I have a big enough shop to work in.

Nope, nice and hard but easy to work with.

EDIT:

Lets say not too soft...but rigid.
