Door-Mounted Pot Lid Hangers and a Return to YouTube

As part of my overall quest to push back the chaos in my kitchen and elsewhere, I made some lid hanger bars out of oak for my pot and pan cabinet. This represents something of a new beginning for me: it's a return to uploading videos to YouTube, but at a much higher level of quality, length, and I hope, entertainment value. This is also a sort of debut of my newly revamped home workshop; I was lucky enough to acquire quite a lot of new tools and machines early in 2020 and I've been integrating, improving, and setting those up ever since. Now it's time to actually make a few things, and hopefully get some interesting videos and other documents out of the experience. Enjoy!

3D-Printed Storage for the Kitchen

Fed up with chaos around my kitchen sink, I designed and 3D-printed a storage tray for my cleaning supplies. It features three compartments for sponges or scrubbing pads and a stand for a bottle brush. I printed this in black PLA, which is probably not a great material choice or technique for long-term kitchen use (FDM-printed plastics have a rough, striated surface finish which probably encourages the growth of bacteria) but I'm considering this a successful prototype for now. I may continue experimenting.

SmartClik Scissor Design on the Market

I'm pleased to reveal some industrial design work I did at the end of 2016 for Washi Scissor, a manufacturer of high-end scissors for barbers and dog groomers. Washi's founder Marc Milman (introductions made by patent illustrator Denis Autridge of ASCADEX) asked for my help developing his idea. Scissors with swiveling thumb rings already existed, but the ability to lock the thumb ring at various angles, helpful to give users mechanical feedback while still accommodating differences in their hands and styles of working, is new.

3D-Printed Impossible Dovetail Puzzle

Here's a 3D-printed version of the classic impossible dovetail puzzle, inspired by a machined metal version by Chris at Youtube channel Clickspring.

After modeling the geometry in Onshape, I printed my version in Estonian blue, black, and white. I wanted to sign my name on the pin so I rebuilt that part in Solidworks, which still offers a less annoying way of importing 2D vector art for this sort of feature. If you'd like to make your own impossible dovetail or play with the CAD models, follow these links:

A Filament Extender Guide for Crystal Palace

I recently documented my designs for a kind of filament extender structure that I added to my 3D printer to keep the filament a bit more under control on its way from spool to extruder. Maybe it will be of use to someone else that has a Prusa i3 clone like mine.
