This a simple magnetic mount for a kleenex box or other tissue box to mount it under a shelf, under a desk, or against a metal wall.

Note

• Designed for 8mmx3mm (2.65mm actual height) magnets
• The internal dimensions are 230mm x 122mm x 95mm, designed to fit standard kleenex boxes with some extra space
• If you have spaghetti detection of some form, it tends not to like these large hex patterned models.

Printing Recommendations

• Can be printed entirely without supports with a layer height ½ your nozzle diameter or less.
• Possible problems with stringing if your filament is wet
  • Recommend using a heat gun to remove strings

Assembly Recommendations

• Use a high strength glue to hold the magnets
• Use needle nose to push the magnets into place
• Align the magnets' polarity if you intend on attaching it to magnets rather than just a ferromagnetic surface

Model Adjustments

• I provided the fusion file, currently it isn't parametrized 
  • To modify the magnet width or number, just modify the sketch and the rectangular pattern
  • To modify the magnet depth, just modify the corresponding extrude function
• If you plan on changing the magnet size/strength, ensure you have enough force
  • Mass of the tissue box fully loaded as ~250g
  • Max nessecary peak pull force to remove tissue ~80g
  • Mass of holder model ~115g
  • Mass of Each of my Magnets ~0.5g
  • Pull Force of each my 8mmx2.65mm magnets ~150g eq
  • Number of Magnets: 10
  • Expected peak downwards force 600g eq
  • Magnetic pull force ~1500g (good for 2x safety margin)
• I do plan on making a parametrized model for my next version
