Uni-wheel - One Wheel Freestyle Finger Board - Compliant Suspension - Fidget Toy - New Sizes and Design

This is a complete redesign of my original “One Wheel Freestyle Fingerboard - Fidget Toy” that I designed about three years ago:

Based on some comments, I decided to make the parts fit together better and to make available larger wheels. Then, I thought that I could make some cool designs, as well as reducing the quantity of filament used. Then, I wanted to see if I could incorporate some kind of suspension, but within the wheel, itself (see the photo showing the evolution). Here are a few of the changes:

• The “Right Side” now fits into the wheel easier, and can also be removed easier.

  • To remove the right side, use a hard, flat tipped object (end of a pen, metal punch, screwdriver, etc.) and push on one of the tabs in an inward direction and toward the center of the wheel. This method does not work well for the “3-Spoke - Compliant Spiral” wheel, because the spokes flex while attempting to push on the “Right Side” tab(s).

• The right and left sides are more comfortable and have deeper cups, for a slightly better hold.

• The side pieces also print flat on the printer bed and require no supports.

• The solid wheel design is now available in three sizes.

• Newly designed hubs and tire use less filament and print faster.

• There are multiple options for spoke styles.

• Compliant shock absorption within the wheel itself has been incorporated in the  “3-Spoke - Compliant Spiral” wheel, which allows for a downward travel of the hub and side pieces of approximately 10mm.

• A display stand has been included, which fits all wheels, except for the  “Solid - Small” wheel; the fit for the “Solid - Medium” is so-so, but it works.

• The new, larger designs work better for massaging muscles in one's forearm ('tennis elbow' - tendonitis, etc.). The “3-Spoke - Compliant Spiral” wheel is a little more gentle for this purpose.

I printed all of my pieces with 100% infill, with 3 walls, and with aligned seams. The models are designed to print in their present orientation (R & L Sides and Display Stand on their bases, all wheels on their sides). Brims and supports are optional. After printing, some light sanding on the axle and hub touch points, particularly the inner seam in the hub, can help the wheel run smoother when fully assembled.
