More downloads will follow, but most of it is ‘work in progress’, so still changing.

Flaps handle

Flaps handle mechanism design SVG and DXF.
Using pieces of adhesive furniture felt from the Action shop for smooth sliding.
At the photographs the top of the fixed part of the handle has an extra 2mm plate because the distance between handle and aluminum guide was a bit too large. The design in the SVG and DXF files has been updated (bent sliding part 2 mm shorter so that the handle comes 2 mm closer to the aluminum guide) so that the extra plate is not needed anymore.

Other projects: cheap Bluetooth keypad based DIY page turner pedals

A small, unrelated CNC project for the summertime when there is less time for cockpit building, but I needed a place where the design can be downloaded.
