A multi part Gridfinity baseplate that fits the drawers of the wide Ikea Alex unit perfectly. My main focus was to make it fit perfectly without much wiggle room while still being printable on a Prusa MK4 sized bed (25 cm x 21 cm).

 

Print Instructions

  • Print parts A, B and C two times each
  • Any basic PLA should work
  • 0.2 mm layer height
  • 0.4 mm nozzle
  • PrusaSlicer speed profile

 

Note

For parts A and C, the slicer may tell you that they don't fit on the MK4 print bed, even though they should (they max out the 21 cm depth of the bed to the millimeter). At least PrusaSlicer does for me, sometimes. It usually helps to delete the part and place it again.

If for any reason this doesn't work on the second or third try, I also had great success with scaling the parts down by 0.1 mm. They will work just fine mechanically and all Gridfinity bins will fit just fine.

Model origin

The author remixed this model.

Differences of the remix compared to the original

The model is inspired by Minos version, but was constructed from scratch.

Significant changes:

  • Changed the cut positions so the individual parts can be printed on a MK4 sized bed
  • Changed the side spacers to be more visually appealing and use less material
