mphardy's remix was very parametric, so after a few additions I got a image. Then I needed more space for my image, so a couple parameter tweaks later I was able to turn the trapezoid to a square.

With the image and a color change or two, it makes a nice 3D printed souvenir to hand out.

Features

• Customizable text content, size and position
• Customizable image. The image you load is converted to a 100x60 height map and embossed on the opener
• Customizable shape between a rectangle and a trapezoid
• Both pre-set and customizable coin slots
• Build a plate of bottle openers right on the virtual build plate.

Notes (mostly copied from mphardy's version)

• Only US 1 Cent slot tested and verified.
• The model is complicated and can take some time to render, especially if you load an image, so be patient!
• mphardy's remix for more details
• The coin should squeeze into the slot after the print is finished.
  • mphardy uses pliers to fully seat the coin in the slot.
  • When I print, I edit the gcode to pause the print right after the last layer of the slot is printed and insert the coin at that point.
• If you add or change any coin measurements, let mphardy and myself know so those changes can benefit everyone
• If you are having trouble previewing your customization on Thingiverse, download the files and make the STL directly in OpenSCAD. If you do so, you may also want to install the build plate library DrLex has good instructions.

Changes in Version 1.1 of this remix

• Added image customization
• Eliminated some non-manifold surfaces
• Made build plate optional
