Condoms Dispenser V2

Last winter we published a condom dispenser design. Here is a new version that is sturdier and easier to build.

Materials

1. 421 grams of 3d printing PLA filament for the top and bottom parts
2. A 90 x 370 mm piece of 3 mm thick transparent acrylic for the window
3. A 70 x 70 mm piece of 12 mm thick transparent acrylic as a weight
4. 2x M3 x 8 mm long button socket cap screws they could also be tamper proof screws...
5. 2x brass M3 threaded insert for 3d prints
6. 4x #8 wood screw for mounting the dispenser on a wall
7. Epoxy or cyanoacrylate glue for gluing together acrylic and PLA

Tools

1. Access to a laser cutter
2. Access to a 3d printer
3. A soldering iron

3d print the three parts (Base, Haut and Milieu). 3mf files are supplied and also an Autodesk Fusion 360 (.f3d) native file in case you want to make some design changes. We used PLA with a 15% infill at a 0.2 mm layer height. You will need to add support material on the base and the middle part.

All laser cut parts are included in the .svg file.

First let's cut the front panel in transparent 3 mm acrylic.

Some weight needs to be added on top of the stack to prevent some "jams" mid-height of the dispenser. We tried using a strip of flexible PETG but it made the refill process more tedious. We used laser cut weights made out of 12 mm thick acrylic. You will need from 1 to 4 of those weights. Unfortunately, laser cutting such a thick material is not a piece of cake for many laser cutting machines. Transparent weight has the advantage of not masking the brand of the product.

Heat the soldering iron up to 210°C. Don't heat too much : the plastic would melt too fast and it will be difficult to install.

Place a threaded insert on the soldering iron as shown then push it into the 3d printed part. Make sure it is properly aligned then remove the iron. That's it!

The 3d printed parts are designed to be inserted into each other. Add a small amount of glue onto each face then insert the part in place and wait for the glue to set.

There are four holes on the backplate of the dispenser. I presume you figured out that they are intended for screwing the apparatus to a wall. Those holes are for #8 wood screws. Don't apply too much torque!

There is not a lot to say on that step! Place the condoms in the dispenser then add the weights on top of the stack.Close the machine using the transparent front panel and secure it with the two M3 x 8 mm long button head cap screw. In our school, those "Allen" sockets screws are enough to prevent tampering, maybe you will need something more tamperproof...

The dispenser have a capacity of around 60 to 70 condoms.

Have fun preventing infections and unplanned pregnancies!
