PlayWell was designed to accommodate as many minifigures as possible while remaining functional. The stud is angled at 70 degrees to the base and positioned toward the front to achieve this. PlayWell keycaps are 3D printed using Nylon 12, and specifically utilizing the Multi Jet Fusion (MJF) technology for quality. This combination of material and manufacturing method was chosen because: (1) Nylon 12 is one of the most durable materials among options suitable for keycaps, (2) keycaps can be printed within reasonable precision/tolerances, and last but not least (3) the keycaps approximate thick SP SA keycaps in typing tests.
Keycaps are individually inspected, retouched, and tested before they are shipped to ensure that (1) MX stem snugly fits various switch types, and (2) minifigure heads slide in and out of the stud exactly as they do on a minifigure with just enough friction. LEGO® parts are manufactured to incredible tolerances and getting the fit just right requires the keycap stud to be produced within +/-0.03mm in diameter. Resolving both of these tolerances to deliver the best product possible means a significant portion of prints have to be rejected or retouched with precision tools by hand.
According to bricklink, the LEGO Group produced over 10,000 unique minifigures over the years. There are over 3,000 unique head pieces as well as over 900 head gears available. That’s more than 2.7 million combinations! You can also order custom minifigures professionally pad or UV printed just like the real thing. More importantly, most minifigures are reasonably priced (and readily available for purchase) or better yet free if you already own them!
