Backpack Ryobi

thingiverse

Getting sore arms from holding that heavy hedge trimmer? Well ... this design might alleviate the strain a bit :-) The idea is to put your heavy battery in your backpack and only insert a lightweight adapter in your trimmer (or other Ryobi gear) to get the weight down. I made af remix of the bottom of https://www.thingiverse.com/thing:1677812 for the adapter insert into the Ryobi - The top part is not modified - so use the top part from the link. I used https://www.thingiverse.com/thing:1194867 for the battery clip but cut some slits (post print) to fit the nickel wire bands I've used. For the connection between adapter and clip I used a standard (thick) 220V wire. In order to get the curly/springy effect of the wire I wrapped it around a metal pipe and used a gas burner to heat it up. See more about the principle here: https://www.instructables.com/id/Make-Coiled-Wire/ The original motivation for this design is my plan to create a custom battery from an existing Ryobi battery with much more capacity - But in order to make this feasible I have to put the battery elsewhere or it will get too heavy :-)
