These are super simple stands that allow thin lenticular images generated with LuBan3D (or any other suitable size item) to be displayed free standing.
 

The profiles may seem like they feature too many walls and too much infill, but that is to ensure that it's heavy enough to hold the image upright without tipping over under it's weight. Even so, they tend to print in just 30-40 minutes tops.

Lengths:

• Short - The short stands are 60mm long and suitable for images up to around 200mm
• Long - The long stands are 135mm long and suitable for longer images

Sizes:
The stands are available in 5 sizes in each of the length versions (10 in total). The difference between these is the size of the gap allowed for inserting the stand. The design allows for a 0.2mm tolerance so the displayed figure is the size of lenticular image they are suitable for, not the size of the gap. 
They are available with gap sizes suitable for holding lenticular images up to the following sizes:

• 1.3mm
• 1.5mm
• 1.7mm
• 1.9mm
• 2.1mm
