E-Twow Handlebar plug

Read this first:
• You need a very good calibrated printer
• You need a M4 12mm screw and a M4 nut for each part
• The nut-hold of the part is undersized! You need to head up the nut with e.g. a hot air gun to press it in the nut-hold
• You need to exchange the handlebar grip with a commercial bicycle grip und to drive a hole of 10mm in the new grip for the handlebar fold mechanism bottom.
If you have read until this point and own an E-TWOW and want to change the grip of your the handlebar, I belive you will be lucky at 95% to find this part...
