R1 Remote controller handlebar mount

thingiverse

This solution enables attaching the R1 Bluetooth remote controller to a 22mm outer diameter handlebar. I use it to control navigation software on my smartphone. The handle bar mount is only 12mm wide and the distance between the handlebar surface and the device bottom is about 11mm. In the original, a clip mechanism holds together the bottom and top parts. Although this mechanism is also used with the "R1 Body lower part", the printed clips are not that strong, which is why an M3 screw has been added to hold everything together safely, including the "R1 Mount adapter" with the slide/lock for attaching the device to the "R1 Handlebar mount". The nut for this screw is placed in a pocket formed by the "R1 Nut holder", which has to be glued onto the original carrier for the PCBs and rechargeable battery. Even though this screw also attaches the "R1 Mount adapter" to the bottom of the "R1 Body lower part", possibly at an angle, the mount adapter is meant to be glued to the bottom once the most ergonomic angle has been found - it's much more sturdy that way. <h4>Parts</h4> * R1 Remote controller (e.g. Amazon-search for R1) * M3 screw with countersunk head, 11mm <= L <= 15.5mm * M3 screw with barrel head + washer, L >= 16mm * M3 square nut * M3 hex nut * 2 small pieces of 1.75mm Filament or similar <h4>Printing</h4> All parts have been printed in PLA with 0.15mm layer height, except for the "R1 Push button" and the top layers of the "R1 Body lower part", which were printed with 0.1mm. Support was mostly designed as optional part of the model, except for the support of the main part which was left to the slicer. The main part ("R1 body lower part") is a bit delicate to print because of the curved top edge with tiny clips that connect to the upper body part of the original housing. PLA might not be the best material for this, PETG or PETT might work better. <h4>Instructions</h4> 1. Open the R1 Remote, starting at the front. The model of the main part shows where the clips are located. 2. For drilling an extra hole into the inner carrier that holds the PCBs and battery, it's safer to disassemble the whole thing. 3. Lift up the battery and remove the 3 tiny screws underneath. 4. Take a close look at how the on/off switch is put together and then take everything out, but be very careful not to damage the on/off switch and the wires of the battery and lower push button. 5. Unclip the PCBs from the carrier. 6. Drill a 3.5mm hole into the carrier where the nut will be placed. 7. Put everything back together like it was before step 3. 8. Secure the square M3 nut in the "R1 Nut holder" with a short M3 screw and glue the nut holder to the carrier between the battery and the vertical PCB holder - as shown in the picture. 9. Insert the "R1 Push button" from the outside into the main part and secure it with a piece of 1.75mm filament or something similar. 10. Clip the main parts together and screw on the "R1 Mount adapter". 11. For the hinge of the "R1 Handlebar mount", another piece of 1.75mm filament or alike will do. 12. After an ergonomically good angle for the mount adapter has been found, the mount adapter should be glued to the bottom of the device (without gluing in the screw though).
