This is my self-Designed Surface Dock made for ease of use and less cable Spaghetti on the Desk.

It is carefully designed to have the Surface easy to slide in and instantly connect with the cable, and it also houses the Surface's Power brick together with the 1.8m cable. I also left space for an Angled USB-Adapter on the USB-Port of the Power brick. The one i used and definitely fits is following:
Amazon.com: QIANRENON 90° Angle USB C to USB Adapter 10Gbps USB 3.1 Male to USB C Female Left Angle L-Shape Connector,Al Alloy Support 100W Charging, for PC Laptop Tablet, 2Pcs (Left Angle Vertical Bend) : Elektronik & Foto

I personally only own a Surface Pro 7, I DO NOT guarantee that this Dock will fit for any other Model.

It's designed to fit in with the keyboard behind the Surface (Display open), someday in the Future i will add additional Print profiles for having the Surface closes / no Keyboard attached.

If you can, please print the Support break-Point in sufficient Support Material, otherwise it's going to be a pain removing them. I apologize for the inconvenience, but it's not printable without supports in ugly Spots.

Also, while it is of course Possible to remove the Power Brick and the Cable from the Model again, it's going to be a bit of a Hassle, so if you travel a lot with your tablet, i recommend you of buying a second Power Supply.

This is the first of my Self Built models I'm actually Uploading to the Internet, so please be nice to me
All tips on improving the model / Print profile are highly appreciated

Also, i know it is probably currently not Printable on the A1 / A1 Mini due to its size, I'll add a print Profile in the Future for that aswell.
