Bike Spoke Name Beads – Custom Letters, 8 Shapes

My kids and the children on the estate are currently out for hours every day on their bikes. This was a fun design to encourage them all and let them get involved in the printing with me. I wanted them to have options in layouts and shapes beyond what I found online. However I give credit to these two users whose models I did use for inspiration. This is NOT a remix however, it is completely rebuilt in openscad using my own work from previous designs in keychains etc.  Bike Spikes — https://makerworld.com/en/models/2728475-bike-spikes Retro Spoke Beads, full alphabet A–Z — https://makerworld.com/en/models/2617269-retro-spoke-beads-full-alphabet-a-z       AI supported detailed text description below:    Spell your child's name around their bike wheel. Type a name in the Customizer and you get one snap-on bead per letter. Each one clicks onto a spoke — no glue, no hardware, nothing to thread on. Everything prints flat and face down Make it yours Any name, including accents and the letters resize automatically so the beads generally stay the same size. 8 bead shapes — circle, oval, rounded square, hexagon, diamond, egg, heart, star. Every point and corner is rounded off; nothing on these comes to a spike so they are perfect for children Some may slightly increase in overall size depending on the shape.  3 fonts — Titan One (chunky), Chewy (rounded and bubbly), Audiowide (techy). Letter height 8–22 mm, plus a nudge slider to sit the letter higher or lower on the bead. Four ways to colour the letter The two layer-swap options work on any single-extruder printer once you pause and swap the filament. SettingWhat you needOne colourLetter engraved 0.6 mm into the face. One filament.Two colourLetter fills the recess flush. Needs AMS/multi-material.Layer swapOne filament change at 0.6 mm — the second colour shines up out of the letter. No AMS.Layer swap (matched back)Two changes, at 0.6 mm and 1.0 mm — only a thin band is the second colour, so the face, sides and back all stay colour one.  Fit Choose your spoke thickness — 1.8 mm, 2.0 mm (most bikes), or 2.3 mm — and a grip of Light, Standard or Firm. The bead has a round seat with a slightly narrower lip above it, so it clicks over the spoke and stays put. Not sure? Print the Fit test first: three numbered tabs, one per grip setting, about two minutes. Keep the one that clicks on nicely. Also included as an option Letters only — the bare letter with no backing plate, if you want just the shapes on the spokes. (Use Titan One or Chewy for this one).   Credit — inspired by Bike Spikes and Retro Spoke Beads (A–Z), both shared under licences allowing remixes. The geometry here is completely built from scratch.
