I needed another QAL-40 mounting plate for my Rollei Compact Traveler No. 1 tripod and measured the dimensions and hacked it into Fusion360. The Model also includes the 1/4″ thread for the camera mounting screw.
I use this screw (the short one) for this plate: http://s.click.aliexpress.com/e/AEybE2B
It is a few mm longer than the stock screw of the plate, but it works with my equipment.
Please don’t use the printed plate with heavy gear. I will use it only for action cams, flashes and mobile recorder. I tested the plate successfully with an EOS 70D + Canon 60mm macro lens + Flash (about 2kg).
This plate fits on Rollei C4i, C5i, C40i, C50i, Compact Traveler No 1, Compact Traveler No 10, CT-4A, CT-5A, CT-5C, M5 Mini, PGA-584, PGA-484, TT-1, T2S.
