Double Jerry Can Holder First Print

For the test prints, this time, I wanted to add metal to the pictures so I ordered each Jerry Can Holder in metal along with the White Strong & Flexible Polished plastic.  For the Double Jerry Can Holder I wanted to make it one piece and have the top part hinge.  I wasn’t sure if I could get the two pieces printed together and have them function good enough so I separated them and printed them as two pieces.  For the plastic version this meant that each piece was polished separately and caused some interesting things to happen.  The pegs on the top piece became slightly smaller and the holes for the hinge part of the top piece became bigger!  This meant that when I snapped them together, the top piece had a lot of play or wiggle to it.

I had added a little structure support on the bent parts of the top piece which worked out very well.  The top is strong enough in general.  The thickness is a little too thin which was from my design.  When the cans are installed it allows the top to move back and forth.  Adding to that sideways movement is the fact that I have a square bottom, inside the base for the cans.  The NATO 20L Jerry Cans taper on their sides so it creates a smaller footprint or base when inside the Double Jerry Can Holder.  I have to revisit these couple of design aspects to correct the issues.

The Metal version of the same Double Jerry Can Holder has different issues.  I ordered it in Matte Black Steel which came out beautifully.  I realized after I received it that the metal is so strong that I can’t snap in the top piece to the bottom.  On top of that the top piece is too wide to even fit between the supports I created on the base.  I can manually grind these down to fit but that defeats the purpose of a ready-to-go product that someone can order and use.  I don’t know if I will have to split the model into printable plastic and metal or if I can work it out in one model.

More testing is needed for the Double Jerry Can Holder.
