Mark Prommel, partner and design director at Pensa, became inspired to design the DIWire clock when he saw the strength of the DIWire being able to create precise, repeated shapes. He began thinking about designs that take advantage of creating forms using single lines and wanted the lines of the object to become integral to the structure of the piece. His final clock design showcases numbers that are the perfect way to utilize the function of the DIWire that would otherwise be very difficult to achieve. 


Once Mark designed the clock, a functioning prototype was developed. The prototype consisted of wooden pieces CNC’ed at a local woodworking shop, clock-hand fixtures printed on our 3D printer, and numbers and hands bent out using the DIWire. To ensure reliable minute hand movement, the minute hand required shortening. This involved finding the balance between maintaining the desired look of the clock and ensuring the hands were rotating properly. Otis tested different metals as well as different hand lengths before finding the right combination.

Once the functioning prototype was completed, a batch was produced as rewards for thirty lucky DIWire Kickstarter contributors. Each set of numbers was bent, their ends cut to length on a plotted print-out of the real-sized numbers, and then threaded one by one on a lathe rigged with a rod threader. To achieve the finish, Thomas Callahan from Horse Cycles mounted the numbers to a perforated sheet and applied a black powder coating. Hands were hung by the center point for red powder coating. To create the face, thirty wooden center pieces were glued together. Once the face pieces were set, threaded inserts were screwed into place for number insertion by the clock owner. The minute and hour hands were mounted to a 3D-printed center piece. The clocks were then partially assembled by placing the movement into the wooden piece.

This first batch of clocks were shipped out to supporters so they could do the final assembly by attaching the numbers to the clock body, and attaching the hands to the movement. The clock garnered such positive attention that the Museum of Modern Art decided to put it into the MoMa Store
