Paint Racks

Emma’s paint collection is getting pretty big. It was impractical to find colors in her basket, so I decided to create some parametric wall-mount removable paint racks to hold her Apple Barrel paint collection.

The Tools

  • Fusion 360
  • Lightburn
  • CO2 laser cutter
  • clamps
  • rubber bands

The Materials

  • 5mm birch wood
  • wood glue
  • drywall screws

The Design

I wanted the racks to be easily removable so I made slots for the screws to easily go in at the ends of the rack. I initially made it to hold 12, but it ended up being too wide.

I would post the Lightburn/SVG/DXF files, however, the design is dependent on the thickness of the material. 1/4 inch MDF ranges from 5.5-6.3 mm. The birch I used was 5mm. Also, the laser kerf (thickness of the laser cut) even though small, may be different than your machine. To do it right, you really need to open the file in Fusion and save the sketches yourself after updating the parameters.

Initial design with handle for easy carrying

The design is completely parametric so the bottle diameter, height, count, and material thickness are all customizable so I can use this to hold anything else like paint cans, sauce bottles and spices, etc.

Didn’t have great clamps, rubber bands should do!

Birch wood seems to have a lot of ash when cut on the laser so I had to take a damp towel to clean off the edges otherwise the glue job is a complete mess.

Mistakes

The stock I used was slightly curved which caused distance issues with the laser’s focal point. Not a big deal, but I should add some weights next time to flatten out the stock

Rubber bands are not ideal for gluing things. After the initial prototype, I utilized some strategically placed clamps and the result was much better. Also, if the wood is slightly curved, I realized that you can use the curve to your advantage to put pressure on the connecting edges.

Espresso Station

This is a little cubby drawer station I made to go with my Breville Barista Express machine. It is meant to store drink mixes, tea, espresso supplies, sugar, cups.

The Tools

  • 60 watt CO2 laser
  • rubber bands
  • Fusion360
  • Lightburn

The Materials

  • 5mm birch plywood
  • wood glue
  • sandpaper

The Build

The main body with mini handles for easy lifting, and a small wall around the edge

The empty space will have a drawer that slides in and out for main storage of tea bags, supplies, etc.

Draw with openings on both sides

I designed the drawer with a 2mm tolerance on all sides and found out that was way too much. I should have done 1mm or less. I put the hole handes on both sides to allow for air to escape because I assumed it would be a tight fit.

My trusty 60 watt CO2 laser

This is my first project with birch plywood. I did NOT know that the middle layers of the plywood were not 100% filled. Surprisingly, this 5mm birch cut much easier than 6.3mm MDF.

Rubber bands and wood glue

Putting together the pieces was messy. I used steel wool to brush off the ash from the laser cuts, but it still got everywhere.

Wood dried and cleaned

I tried to sand off the dirty ash, but found out that a damp cloth worked even better to clean up all the dirty ash from the surface.

Finished product

I engraved a little coffee logo on the front just for fun. In retrospect, the design is much too long, I could have made it a little more compact.

Mistakes

  • top-front piece was designed with no interlocking joint and relies entirely on glue
  • the 2mm gap tolerance for the drawer is way too much
  • tried to sand off ash instead of wiping it down
  • design too long, need to shorten it
  • found out i added tolerance to BOTH pieces, doubling up on the gap
  • need to engrage the logo a bit darker next time
  • need to round off the fillet on the handles more to match the drawer handle

Updates

Redid the design to make it shorter, also fixed the front top piece so that it interlocks properly. I also burned the espresso logo in the front darker and rounded off the fillets.

More reasonable looking
