Strap Holder for Phone Bike Mount

Inspired by other strap holder available here, I designed this holder to fit the popular Phone Bike Mount. All you have to do is melt two threaded inserts for M4 screws into the Phone Bike Mount. It fits this Phone holder:

and of course also the original it was remixed from.

As the distance between the two would be a limiting factor with just holes, the holder features two slots fitting M4 screws. It's STRONGLY recommended to use M4 * 10 panhead Allen screws, because they have the lowest heads (~2.25mm). Every other screw will make mounting a strap difficult, especially with V1 of this holder. I used the standard M4 inserts from CNC kitchen. I think the shorter ones would be fine too if you only attach light stuff. The used strap can be 22mm wide.

As seen in the photos, I just use a strip of MTB tube for attaching stuff. Especially now, during transition from winter to spring, I want to remove long gloves or a helmet hoodie without stopping and putting these into my backpack. This was the main idea behind this holder.

There are two versions: V2 for screws at a greater distance, and V1 for screws that are closer together. You'll have to figure this out yourself. I haven't done a study with different distances :-) and if both screws are reachable with the Allen key. Mine are ~25mm apart, V2 works fine here. If you choose the wrong version, only one bolt could be reachable with the key. Printed in PETG with 5mm brim and 100% infill and complete support for the two bars., I don't want to loose stuff if it breaks. Takes only 15 minutes anyway. When using this holder, obviously you cannot mount your phone on the bike. 

All this was done in 3 hours on this beautiful Sunday morning, isn't 3D printing amazing?
