DIY IBM Selectric kind balls give ’60s typewriters new life (and Comedian Sans)


There are some emotions you simply cannot re-create. And to IBM Selectric loyalists, neither beam spring keyboards nor buckling spring designs nor a contemporary mechanical keyboard can replicate the distinct really feel pushed by that legendary kind ball. Within the ’60s and ’70s, the Selectric was an workplace staple, however the development of PCs and daisy wheels compelled the machine into retirement by 1986. That hasn’t stopped folks from shopping for, restoring, and selling Selectrics, although. The issue is, IBM stopped making the only printing aspect that makes these typewriters so particular. Yow will discover the sort balls on-line, (together with choices claiming to be used and never used) and at shops carrying previous digital elements. However you’d save time and sources for those who might make your individual. It took years for somebody to discover a option to make the Selectric golf ball 3D-printable, however now somebody claims they’ve.
A tinkerer named Sam Ettinger not too long ago shared his Selectric kind ball 3D-printing mission on Hackaday and Github and shared the information on Printables, as reported by Hackaday. However beware: These finalized variations have not been examined or printed by their creator. Earlier this month, Ettinger shared a video on Mastodon of the prior model in motion, admitting that some letters weren’t usable.

The brand new fashions are reportedly 0.2 mm shorter to handle this and regulate the letter rotation, because it was “90 levels off.” Due to this, we will not confirm how profitable these fashions could be in actual use.
Comedian Sans and extra

Moreover eliminating jammed keys by shifting from old-school typewriters’ kind bars, one among Selectric typewriters’ niftiest options was the flexibility to swap out golf balls and alter the typewriters’ typefaces and languages, from worldwide languages to the APL programming language and scientific notation (for those who want extra assist understanding why individuals are nonetheless hooked on Selectrics, this YouTube video from keyboard fanatic Chyrosran22 might assist).

Ettinger’s kind balls comply with this identical spirit by providing Comic Sans (drawing from Jesse England’s 2014 Comic Sans typewriter), in addition to Windows’ Tifinagh keyboard layout within the Ebrima typeface and Home windows’ Cherokee Nation keyboard layout within the Digohweli typeface. Every ball requires a “bent wire,” the Printables pages say, or Selectric ball clip, for which designs are additionally out there by way of Printables, to be able to work.
Constructing on earlier work
Ettinger thinks these DIY golf balls enhance on earlier makes an attempt, attributing due to the work of Steve Malikoff, which made an bold, however flawed, DIY-type ball utilizing OpenSCAD. In 2020, Malikoff detailed efforts to 3D-print his kind ball with an FDM printer however struggled to make sharp edges on plastic.
Ettinger, turning to the powers of a resin printer, mentioned he modified “most” of Malikoff’s kind ball dimensions and the way the characters are generated for the automated course of.

With its superior capabilities, from mistake correction to introducing magnetic recording expertise (good day, early digital phrase processing!), you may’t have a real dialog about how we obtained to fashionable computing enter with out nodding to the Selectric. These devoted to the legend might now have a brand new option to preserve their machines alive—or no less than helpful work to construct upon.
We sit up for seeing somebody print out and check Ettinger’s fashions to verify in the event that they do IBM’s machines justice. Even higher, folks might use Ettinger’s work to create extra choices for DIY balls, from extra typefaces to extra languages and maybe even higher designs. Lengthy dwell the golf ball.
Correction: IBM’s Selectric balls aren’t product of steel.
