My beloved Cube Hybrid performance has a design fault which is the battery cover button not engaging properly and the battery cover dropping off during a ride, a quick google you will see this is a major issue across the Cube ebike range.

I got lucky, a neighbour found it undamaged but not before a day had passed with me trying to get a replacement.

Getting a replacement is not that easy, the button and plastic are sold separately and trying to find a complete button is nightmare as most places sell that in 5/6 parts as well so all in all its around £60/80 to replace and that can turn into weeks due to low stocks.

Yo can easily just strap it with velcro to stop it coming off but I wanted my strap attached to the cover so I would never forget it and it would strap on the frame without moving.

20mm velcro with buckles used, off amazon around £5 - https://shorturl.at/eq9Q2
M4 screw and nut

Put your cover on and a strap and line up where you want it, mark it and remove and drill a 4cm hole in the centre, thread the velcro through and make a hole in the velcro for the screw rest is pretty easy.

Then never worry again about it dropping off.

Printed in ABS but petg will do, dont waste time with PLA
