My partner was unhappy about the handle he bought for Wahoo for Rose Reveal bike because it was unstable and was tipping. As a result I took part for Xlite bike and modified it in Prusa Slicer to make it possible to attach to Rose Reveal that has similar but a little different dedicated mount.
The Revel has different angle than Xlite and the holes seem to be spread on a different distance.
I adjusted it for the plates that he got with the handle he though would match - it is not a typical plate for all of the systems like Garmin, Wahoo and Bryton but changing the diameter and extra holes should be easy.
Printed this with snug supports on build plate only. Originally M5 short screws are required. I used M4 - I put nuts underneath using a knife and a piece of tape as the original thread was already damaged.
I added a m3 nut inside and space for 10mm m3 crew for the wahoo plate to maintain the option to mount a gopro attachments.
The author remixed this model.
Made it to match a different Rose bike Reveal that has a similar but a different mount point
