I've built a few of the vk3il pressure paddles mentioned by the Peters, 1 for each kit, and love them and am probably tossing all my other portable paddles (all 3d printed ones) in the bin to never be seen again. They are a treat to use. Never needing adjusting as there's no moving parts, sensitive but just the right amount, light, and take up virtually no room in my kit... what's not to love.?
