Battery Organizers

I saw these battery organizers when I was searching Thingverse and had to share them.  I printed them on a Divinci Jr. printer from ABC Printing.

Each battery holder requires printing from three files:  cover, holder and label.  I use 3D Fuse to assemble my PLA (Polylactic Acid) models.  I tried using super-glue, but the results were less than satisfactory.  I used my experience in Medical Device manufacturing and, even though we never used PLA, I thought the solvents we used could be an alternative.  The 3D Fuse contains MEK and several other solvents, so the plastics are actually fused rather than just having a mechanical bond.

These clever holders have “key holes” so you can hang them on a peg board  or just on nails on the wall!

HACKS:

1)Adhesive in a tube can be messy and hard to control.  I searched online for adhesive dispensers (I didn’t go with the $5000 model that manufacturers use) and found some syringes with blunt needles for about $8.  I got an assortment of sizes of both syringes and needles along with caps to seal when not in use.  These allow for very precise adhesive application.

2) Those of you famiar with 3D printing may have noticed that the print bed does not have bed tape.  Bed tape (on my printer) is like a 6” x 6” square of masking tape.  It is used to hold your object in place while it is being printed.  One day I cut a big gouge in my bed tape and didn’t have any replacement.  I went down to the local big box store hoping that I might find some wide masking tape.  Maybe I could use two strips side by side?

The trip was to no avail.  I remembered a shop promoting STED for Jr. and Sr. High school students that offered some 3D printing classes, so I called them to see if they might have some tape.  They didn’t have any tape, but they told me I could rub glue stick onto the glass surface of the print bed.

I found a glue stick in my “everything” drawer and rubbed glue all over the print bed.  It worked fantastic!  … Too fantastic.  I found that I had applied too much glue and my objects stuck very tightly to the print bed.  Since then, I have learned to coat the print bed lightly and then gently spread and smooth the surface with a finger wetted with water.  If you get a gouge in the surface you can repeat the spreading of the glue adding only what you need to make the repair.  A thin film is sufficient to hold your object.  I think this works even better than the tape!
