Workshop

Personal projects designed and made at home, mostly on the printer farm. Some became products. Most solve a specific problem in the car, on the camera or around the house.

Vortex drink dock

A bicycle handlebar drink holder that grips a can or bottle and releases it with a twist. About 15 iterations in, and close to market.

The current product project. The holder locks a drink in one direction and releases it with a twist of the hand, so it can’t bounce out on the road but comes free easily when needed. The cup is a single TPU print, so there are no springs or hinges to fail, and it mounts to the bar with a separate rigid clamp.

The design is on roughly its 15th iteration, and each version is tested in daily use. Current testing shows it working very well, and it is close to ready for market. This entry will grow as it progresses.

35 mm film case and accessories

A snap-shut case that keeps three rolls of 35 mm film upright, plus a timer stand and an MR2 shifter cup. All designed for printing.

Loose film canisters rattle around a camera bag. The case holds three rolls upright, with a round pocket in the lid over each canister. The lid hinges on printed knuckles and closes with a printed snap latch. It was produced in black and white.

The same range included a tilted desk stand for a round timer, and a cup that fits around the MR2’s gear shifter.

2022–nowOngoing

Print farm

More than 10,000 parts produced, including the production run for the film scanning business. Each machine tuned individually.

The farm has produced more than 10,000 parts. A Bambu Lab A1 is now the main printer, alongside four Sovol SV06s; an Ender 3 V2 and a Kingroon have been retired. The Sovol and older machines were moved onto Klipper firmware and tuned with their own configuration, calibration prints and slicer profiles. Every machine had a validated print file for each product, which kept batches of film carriers consistent. Newer prototypes, like the hand reel, run on the A1.

Track cars

A Toyota MR2 and a Volvo C30, built and raced from the home workshop, with printed parts and a wireless tyre temperature sensor in development.

Both cars are maintained and modified in the home workshop, with repairs done in-house. Parts that are hard to find are modelled and printed.

Tyre temperature logging (in development). For track days I am adapting RejsaRubberTrac, an open-source wireless tyre sensor published by MagnusThome on GitHub. An infrared array reads 16 temperatures across the tread, and an optional laser rangefinder logs suspension travel. The firmware port to a Seeed XIAO nRF52840 board reordered the sensor start-up, slowed the shared I²C bus for reliability, added a reset for the rangefinder, packed the readings into 20-byte Bluetooth packets for the RaceChrono lap timer app, and added battery monitoring. It has been bench-tested so far and has not yet run on track.

Camera lens hoods

Slide-out hoods that give vintage Leica Summicron lenses the built-in hood of the modern version, plus a slim hood for a Fujifilm compact.

Modern Leica Summicrons have a hood built into the lens that slides out when needed. The older Type 4 lenses from 1979 to 1994 don’t. This hood stays on the lens permanently and slides in and out like the modern version. A low-profile rectangular hood does the same job on my Fujifilm compact.

Supra cup holder

A printed insert that sat flush in the centre console of my previous Toyota Supra, after three revisions of the top plate.

The console was measured, then the insert was modelled and printed. The top plate went through three versions before it sat flush. It holds a standard can or a travel mug.
