iGPSport holder GoPro mount

After i bought iGPSport bike computer with bundled holder, it turned out that i want also to mount gopro or flashlight to it.

Unfortunetly it have some strange cross-like petrusion in down facing side.

Of course i could replace this holder by just buying new one for couple buck (literally - they cost like $2.50), but why we all have those expensive 3d printers for?

Print laying down, with PETG or ASA. Because its a small detail i suggest 0.25 nozzle.

You will also need to replace original bolts by 2 pieces of M3x12
