Customisable Wheel of Fortune Random Spinner with Swappable Segments [MMU/Non-MMU]

Fully customisable random spinner wheel with removable and swappable segments. Prints as several individual parts and is easily constructed. A rack is included to hold your extra segment sets.

Either use the example segments provided (quiz categories), or come up with your own! Here are some ideas:

• People's names (for picking someone for a task, first player in a game etc)

• Takeaway food

• Drinking game actions

• Days out

• Numbers

• Forfeits

What you'll need

• 608 bearings - minimum: one; recommended: two

• 500-750g filament. Multiple colours recommended but not essential.

The wheel works with a single bearing, but is considerably more stable with two. Make sure you pick the right frame version for the number of bearings as the axle length and inclination are different in each case.

Customising

To customise the wheel with your own categories, open the 'Random Spinner' file in Fusion and adjust these parameters;

Both the 'Segments' and 'Segments (Debossed)' components (for MMU and non-MMU respectively) will update automatically as you alter the parameters above. This is usually a seamless process, but occasionally Fusion will get confused and fail to cut the letters out of the MMU version correctly. If this happens you'll need to switch to the context of the problematic segment and go back through the timeline features to correct the issue. Briefly, the text is cut from one body, then that body is diffed with a second to leave solid letters that fit inside the spaces in the first body.

Isolate the finished segments in the editor (Right-click -> Isolate), then export them in your preferred format via the File menu. 

Printing

I used PLA for everything, but you might choose PETG for extra strength.

Base

• I recommend printing with 30-50% infill to give it decent weight.

Frame

• Has two separate bodies - the frame itself, and the axle the bearings attach to.

• Print on its back, with the axle pointing upwards.

• The frame need not be too heavy, but does need to be strong, so 25% infill with a gyroid pattern should do it.

• The axle is the part under most stress, so print with 100% infill for maximum strength.

Wheel

• Print on its back.

• 50% infill recommended to give it plenty of angular momentum as it spins.

Segments

• Print front-side down i.e. with the letters on the print plate. I used a rough-textured plate for a matte finish.

• If printing the MMU version, there are several separate bodies that may be coloured individually. Both the letters and the stripes at the top and bottom are called 'Letter', should you wish to colour those differently to the rest.

• The non-MMU version is a single piece.

Clicker & Pointer

• No special printing requirements.

Rack

• No special printing requirements.

Construction

1. Insert the clicker into the slot in the middle of the base.

2. Insert bearings onto the frame's axle.

3. Insert the frame's legs into the holes in the base.

4. Push the twelve segments into the grooves in the wheel. They can be a little tight - try to apply force evenly at the front and back. Ensure they're pushed fully down.

5. Push the wheel fully onto the axle.

6. Insert the pointer into the base's forward slot.

To remove a segment, take the wheel off the axle and push the segment's outer rim up from the outside of the wheel.
