ALL MODELS IN PICTURES ARE AVAILABLE IN PRINT PROFILE! NO AMS REQUIRED. BEST RESULTS IN TPU.

Description

My motivation for designing this was twofold. First, I wanted a customized/modular bar mat that I can easily disassemble and could do more than just catch spillage. I wanted something that took my bar tending to the next level and gave me options for all the niche cocktail bar things.

The second reason was that I noticed the exorbitant prices that are being charged for bar mats with little to no option for customization. I figured the 3D printing community could do better. So 1900+ lines of OPENSCAD code later, I created this customizable bar mat set.

The modular accessories in the pictures are built with a 150mm width. You can make it any width you'd like, but if you want to make attachments for what is in my print profile, you'll have to make it with a 150mm width. 

I encourage people to make their own accessory adaptations and post on Maker World!

Use Cases

• Bar Mats
• Salt Rimmer
• Shot Glass Holder
• Accoutrement Holder
• Cocktail Pick Stand
• Customized to tricky spaces
• Keg or Tap Drip Tray
• Branding with your Logo

Customization Options:

Shapes (11 types)
Patterns 16 types (hole or extrusion)
Dovetails
Logos (SVGs included in ZIP file or can be uploaded from elsewhere ie pick your own logo!)
Cut Outs  (customizable)
Borders (4 types)
Text (lots of fonts))

Of course, everything can be shaped, sized and moved along the x/y axis to ensure it meets your total customization needs.

Print Settings and Post Print Processing

Common:

• Don't forget to calibrate the build plate before printing!
• Ironing, provides smooth professional looking finish;
• Arachne enabled, for better text printing;
• No AMS required (good for TPU). Learn to switch filaments manually here
  • Default heights of borders, text and logo 0.4mm higher than patterns to support colour change
• Modular to fit most print bed sizes (A1 mini compatible).

TPU

For TPU I recommend Printing out shot glass bar mats to test print settings before getting into the bigger mats

• Slow print
• 1.3mm retraction
• 8% infill for flexibility. Use 12% if you want something a tiny bit sturdier
• Low stringing. TPU is difficult to print. If you get strings, use hot air blower to clean up any remaining strings
• Tolerance: default setting is 0 due to TPUs flexibility

PLA/PETG

• Fast print
• Inflexible
• No stringing
• PLA/PETG Dovetail Tolerance: change to 0.2

Food Safety:

Follow food safety guidelines for 3D printing, ie do not let things you ingest touch your 3D prints. To do this, I suggest using aluminum foil for the salt rimmer and to not let any food touch the mat on the cocktail pick stand if you intend on eating it.

The Future - Commercial Licence:

I may be presumptuous here, but given the $30-$50 price tag for simple bar mats with less customization, I can see this parametric bar mat generator being a profitable option for creators that are looking to sell their wears. Alas, I need more followers before I can offer Commercial licences for this, so please like and follow if this interests you!
