It´s a remix of mathiasdela´s design.

I wanted to have a moveable handle, to lay it flat if the tray is in the shelf but one that will stand if I have the tray outside at work.

The design is made for 6 or 10 batteries. More would be possible if I remix one part, but I think it makes no sense because it will get heavy then.

On my A1 mini the parts have a snug fit. It could be that you have to carve the edges of the handle rotation points a bit, depending on how easy you want to move it.

It was printed with PETG Wasserblau from Bavaria Filaments.

To mount the tray, you have to take the two parts with one hinge on the top ("out 6" or extension “10”, put in the handle an lay it flat on the side.

Then slide the “middle” part from above over the dovetails and press it down (in my case it snapped a bit). Gravity will do the rest, I think there´s no glue needed.

Will do the same for Bosch Professional, soon. Literally they would fit here as well, but they wobble a bit and don´t klick in the fastening grooves.
