Like little L*go Minifigure hands for your Multiboard!  I originally made this clip to hold lipstick or chapstick for my daughter's Vanity Multiboard Set but quickly realized that it was functional and scalable!  For now I have adapted it to have 6 sizes and added the longer press-fit hex back for the Multiboard.  If there is interest I can add a set of bolt-locked clips and more sizes too.

Sizing: One set of all 6 clips uses just 20g of filament so the easiest way to end up with the correct size may be to print a full set to test and then print duplicates of any sizes that work well for your needs.  The smallest clip is good for a chapstick (~16mm), while the largest is good for a D-cell battery or small spray can (~32mm).

Using Versatile Clips: These clips will work in any of the snaps that you used to mount your Multiboard to the wall, but can be placed elsewhere on the board using standalone Snaps such as the Moderate Weightbearing Snap

Here is a list of sample uses for the various sizes:

First number is the scale compared to the smallest size, second number is approximate internal size. Sizes of clip will vary for most examples but are intended to give you some ideas.

• 1.0 (15.5mm) - Chap Stick, Lip Stick, Nail Polish Bottle, Large Felt Pens
• 1.1 (17mm) - Sharpie Highlighters, 
• 1.2 (18.6mm) - Thick Pens, Flashlights, Glue Sticks
• 1.3 (20mm) - Paintbrushes and other Brush Handles
• 1.6 (24.8mm) - Broom/Brush Handles
• 2.0 (31mm) - D-Cell Batteries, Craft Paint Bottles, Small Spray Bottles, Thick Broom/Brush Handles
