First of all the disclaimer: Anyone can print and use the files private and the 'hook' at their own risk.
You can print it online or at your own 3d printer or where ever you want.
I tell you how I did it. You can do it however you want. A colleague printed it for me, the settings are the settings of his printer.
The 2-sided adhesive is from 3M, black, 20 mm with the p/n VHB-5952
The settings of the private 3d printer (you will find it on online 3d printing platforms as well):
PETG with carbon reinforcement (I don't know if this matters).
Printing method: Fdm print, layer thickness 0.1 to 0.2mm, inner strength 25%
The editor of the files is mac-alex from zroadster.com. He gave me the authorization to share it here. If you want, you can donate him what ever you like on his paypal account.
Please send me a private message with your e-mail address and I will send you the 2 files and the paypal address of mac-alex for donation.
