I just modded the thingverse camera mount to allow for ground sensors operation. I also was looking closely at that same tab, thinking it was too small and not thick enough. I printed one, and it appears to work fine, but I think I'll print the new version with the thicker tab just in case. Did the mount still hang onto the gear 360? (Thats what I printed mine for.. the gear 360 2017)
I also created some front leg extensions and a rear shorter leg extension as well.... all the extensions I saw seemed far too short to give the gear 360 2017 clearance from the ground. The front legs have about 30 minutes still to go to finish printing before I can see if my cleverness paid off.
The design, BTW was actually a guy from the facebook Mav group. He released the first version on thingverse for free, and suddely started seeing everyone on ebay and every chinese seller selling them. He adjusted to to clear the sensors, but decided to only sell them on shapeway because of all the people selling his design without getting compensation for the design.
