Kệ Chai Rượu Modular (Parametric) – by Pred

I did like the idea of the original model, but not a fan of press fit and the arrangement the original had. The F3D file was hard to use (to me), so decided to redesign it a bit, which ended up in a full rebuild of the model (pretty much from scratch).

Initial upload

Printing

Use a material which is not too rigid (I used PETG) to print, my settings are:

• Material: PETG
• Nozzle: 0.4mm
• Infill: 10% gyroid
• Layer height: 0.2mm

Module availability

I uploaded the modules needed to build a rack, no special needs are fulfilled (See the file descriptions for details), however the source file (Fusion 360) is attached, use it to build your own module. I attached step files, personally I have better experience with them. Feel free to export your modules in 3mf or stl.

File naming convention

BottleRack_D[AAA]_S[B]H[C]_H[DDDDDD]_L[EEEEEE]

• AAA is the diameter of the bottle (the hole) in mm
• B is the number of segments (1-6)
• C is the number of hubs (1-6)
• D is a “bitmask” telling you which hubs are present (counter clockwise)
  • X - hub does not exist
  • 0 - hub exists, but no connector (rounded corner)
  • 1 - hub exists with a connector
• E is a “bitmask” telling you which outer lips are present (counter clockwise)
  • X - lip does not exist
  • 0 - lip is present
  • 1 - lip is not present

Example

BottleRack_D100_S5H4_HX0001X_L00001X is for a 100mm diameter bottle, has 5 segments and 4 hubs all between the segments and only the last one has a connector. There is one outer lip at the last segment. (This is the top-right corner piece).

Parameters

bottleDiameter

The maximum size the rack can hold

bodyThickness

The maximum width of the body (this is at the hubs)

bodyHeight

The height of the body (when printed with the lips on the print plate)

tenonWidth

tenonDepth

The depth of the tenon

tolerance

The tolerances used for the tenon and the mating surfaces

bodyChamfer

The size of the chamfer on the body (top and bottom surfaces)

bodyFillet

The size of the fillet used for the hubs which have no tenons on them

lipWidth

The width of the lip at the back/bottom of the module

lipThickness

The thickness of the lip

Usage

Most combinations of the segments and hubs are prepared as separate components in the file, however the exact configuration needs to be adjusted manually. (Too many variations to effectively handle it via parameters in Fusion - or I don't know how to do it :) )

Select the component you would like to print (say S3H2 for a half circle with 2 hubs on it).

There will be a few features on the timeline for the component (these are pretty much the same for each component). Some might be suppressed, unsuppress to use them. They are suppressed when all hubs have tenons (none needs to be removed).

Make the sketch under the main component visible and hide all other components. That sketch has all the elements necessary to configure the module.

To remove a tenon, edit the first and second extrude feature (the first one removes the tenon, the second one will fill in the corner). Adjust the fillet (select all corners where the tenon was removed).

The third extrude is the lip, select the ones you need and unselect the ones you don't. If you don't want any lips, suppress the feature.

Adjust the offset face, add/remove faces as necessary. All meeting faces needs to be added and move by half of the configured tolerance value.

Finally adjust the chamfer.

Make sure that everything is good and export the body.
