High Density, No Spill Storage (Mounted or Mobile ! ! !)

prusaprinters

This is a set of close tolerance parts to store and/or transport parts even as small as Surface Mount Components without spilling or becoming disorganized. The "drawers/trays" rotate out of the closed position on a single, metal pivot shaft. The pivot holes in the housing and the holes in the individual drawers are close tolerance (the drawer pivot holes can be reamed to improve the smooth motion of the rotation). [A wine cork is shown in some pictures for scale reference] The drawers are held closed by magnets and there is a small finger groove in the front corner of each drawer to be able to open only one drawer at a time. Sanding the upper and lower surfaces of the drawers for proper fit, makes this movement very smooth and reliable. #4 Flat washers are glued into printed recesses in the body. These washers are the attraction surface for the magnets glued into the drawers. Countersunk holes (4 each, on two faces) are designed into the "body" print to allow it to be attached to a wall or other surface on the left face or the rear face of the body. This unit holds 8 drawers/trays. You can stack "sets" of these units in contact vertically or space them slightly horizontally (to allow for drawer movement). The usable depth of an individual drawer is 0.500". I have included a file to print 20 drawer dividers which can be glued in the locations of your choice with CA or another adhesive of your preference. The drawer dividers will print slightly taller than 0.500" on purpose. This will allow you to sand the upper surface of the dividers to be absolutely flat with the upper surface of the drawer perimeter walls(after they are glued in place). Also, in the event that the dividers lift slightly when printing on your 3D printer, you can still glue them in place and sand the "curved tops" truly flat for a perfect seal to prevent very small parts spilling. I have included pictures of my first version unit only for historical reference (there are printed labels visible on the drawers of ver. 1) . On that 1st version, I printed "live latches" that flexed and followed an arced surface behind the drawer. The latch captured a small groove to hold the drawer closed. This worked very well but added time with more parts to be printed and assembled. The dimensions of the width of the body of the 1st version were slightly larger overall (due to the hidden, internal "live latch". This is my first ever design posting....anywhere. I hope you find it useful. Also, I am not completely sure which licensing option I should choose. :-) If you have questions about my design, please feel free to contact me.

Some sanding may be necessary for best fit during assembly.
