Casio Style Watch Holders for Various Wrist Sizes, No Supports Needed

These are my watch stands designed to be “compatible” with Casio’s black shipping watch holders. These stands can be used side-by-side with original black retail display stands so you do not have to print as many holders.
These are designed to be printed in 2 parts and then assembled, so there is no need for support material during printing. They snap together securely but reversibly, and stay together without hardware. Optionally a M2x10 screw can be used to secure the 2 parts together. They are strong enough to hold up the heaviest metal bracelet watches (e.g. Bulova precisionist divers with steel bracelets) and able to withstand drops from 2m without failure.
They are “compatible” with casio holders in the following sense:
-The base and box at the base is the same size and height
-They are similar in appearance, holding the watch dial at a similar angle and height
-They have a slot on the front to hold a “casio” display tag
-They share the same base footprint and desktop bounding box volume. This is useful if you are designing a holding case where you are displaying rows of these holders.

The watch holders are available in a variety of sizes, from 6.0inch up to 8.5inch.
– For strapped watches (i.e. strap with holes and buckle), this won’t matter because you can do up the strap to any hole to match the holder. The Casio default holder corresponds to the 7.5 inch version.
– For bracelet watches (i.e. with rigid links and pins), the holders are elastic, meaning the 7.0in can accommodate a watch bracelet adjusted for between 6.75 to 7.25 inch. If you try to put a bracelet sized for a 7.0in wrist onto a 7.5in holder, it won’t fit due to being too small, and if you try to put it on a holder that’s too small, it will droop and look sloppy due to being too loose.
– The best way is to measure your wrist circumference and just print that size for all of them.
These holders have been thoroughly end-to-end tested and refined over many iterations for my own personal use over the past 4 years. I have already printed over 4kg worth of them and tried numerous variations to optimize their ease of use, ease of print, and durability over time.
This model is designed for FDM printing in PETG. Other materials are untested.
The wall thicknesses have been optimized to print with 0.6mm nozzles or 0.6mm extrusion width.
