Benriner (mandoline) julienne triple blade holder - weighted

The Benriner kitchen slicer is a staple kitchen tool, being much cheaper than the European brands of mandoline. I love mine. The julienne slicer / comb style blades are excellent, but they tend to get lost on the bottom of the drawer, and the blades are so fine they can get damaged rattling around. So I built this. The idea is to store it with blades down so they're protected. But you can see which is which because of the non-linguistic markings beside the slots, marking the 2mm, 4mm, and 8mm cutters.

The slots are loose enough to make it very easy to get the blades in and out. The top and bottom edges of the slots are curved in case you want to draw them out by tilting them like pulling a book off a shelf.

The sliced version of the file includes two pauses. 

• The first is shortly before the top layers start, so you can add weights inside the grid infill if you want. At 15% infill you can use .177 cal BBs (4.5mm steel ball bearings) two per whole grid square, and it's nicely weighted. Don't try to pack them into any of the holes they don't fit in easily, and make sure none are sticking out the top at all before you restart the print. (I got the idea for this from this instructable: https://www.instructables.com/DIY-Space-Mouse-for-Fusion-360-Using-Magnets/)
• The second pause is a color change, so that you can make the comb size markings in a contrasting color for easy reference. (This uses so little filament that you can actually use up odd offcut bits of filament for it, like the 10cm bit that broke off when you pulled it out of the spool side hole.)

Hope it's useful! Makes and ratings appreciated.
