The H.O.L.D.

If you're like me, you own a Onewheel. Onewheels are an awesome, fun way of transportation around your city. They could almost be considered perfect, keyword almost. The only flaw in a Onewheel is its lack of cupholders. It is commonly known that every wheeled vehicle requires cupholders for peak performance.

Introducing, The H.O.L.D. Standing for Handless Onewheel Liquid Depository, The H.O.L.D. does everything your hands shouldn't be doing while you float on your Onewheel. The H.O.L.D. holds your cold Polar Pop and most other soda cups so you don't have to.

In this instructable, I will show you how I created The H.O.L.D. and allow you to make your own!

All you will need is access to a CAD software, a 3D Printer, some Velcro, and your Onewheel.

I decided to sketch my idea for The H.O.L.D. on a piece of paper first. This helps me be able to visualize how I will draw my idea in CAD and it gives me a place to write down my measurements in the next step.

Measuring is a crucial step in the design process. "Measure twice, cut once" my dad always says, except this time its measure twice, print once.

I measured from the Onewheel and the cup so it will fit.

To draw my design out, I use OnShape, a easy to use and browser based 3D design software. When I draw something in CAD, I like to draw it how my 3D printer would make it. So I started with a base rectangle and drew the attachment triangles from there. I then extruded it like a 3D printer would and added slots for the Velcro to go through. After that I added fillets in many places to make it look better and easier for the printer to handle.

For the cupholder part of the model, I duplicated the mount model and undid everything down to the initial sketch. I used this sketch to create the other half of the interlocking system. After that, I added the circles for where the cup would fit into, using measurements from a Polar Pop I had. Then, like a 3D printer, I extruded it upward to the correct thickness. After some more fillets, it was done.

My CAD Models in STL format

Step 1: To 3D print something from CAD, the first step is to export the drawings as an STL, the file format that my slicer can read. A slicer is a program that takes STLs and "slices" them into layers for a 3D printer to print. It lets you change heat and speed settings, as well as layer height. I use Cura 4.6, a free, super easy to use and professional software.

Step 2: After setting all the settings and getting the printing bed ready, its time to print! I have a Ender 3 printer. Super cheap and arguably one of the best home 3D printers. For the first layer adhesion, blue painters tape has never failed me, especially when printing in PLA. Some good PLA brands are Hatchbox and Overture, both can be found cheap on Amazon.

Step 3: Sit back and watch as your 3D printer prints the parts. Remember, the first layer is the most important layer, if it isn't flat and practically perfect, try re-leveling the bed to make it perfect!

Now, slide the cupholder onto the Onewheel mount and attach it to the Onewheel! I used some 1 inch wide Velcro do accomplish this. First, loop the Velcro through the slots in the mount and then around your Onewheel. And that's it! You have successfully attached The H.O.L.D. to your Onewheel. Now you can ride around with style knowing you have just unlocked the full potential of your Onewheel.
