XTEInk X4 Pro dock for the Sprinkle 3D printed cover

The XTEInk X4 Pro is a great little e-ink reader, but it's also very small and thin, which makes it very fragile. I looked at some commercial alternatives for cases, but was unhappy with them. I then found the Sprinkle XTEInk X4 Pro Case which I use and love, but it didn't work with any other 3D printed charging docks I could find online.

This model allows you to charge your X4 Pro directly in the case, in a convenient desktop dock. It also holds the pogopin and USB-C cable securely in place, preventing unwanted disconnections.

Features

• Simple print: No supports or brim needed.

• Precise fit: The factory Pogopin/USB-C adapter fits entirely by friction. Push it in as far as it will go and then plug the USB-C cable.

• Easy operation: To charge, just lay the X4 Pro + case on the dock. The magnets on the charger will hold the X4 Pro in place.

• Easy to remove the adapter: The design includes a hole on the left side so you can push the pogopin adapter with a small screwdriver to pop it off.

Printing Instructions

• Just download the STL file and use the "Auto Orient" feature of your slicer.

• No brims or supports needed.

• Please note: The pogopin adapter fits very precisely. If your printer is not calibrated and the fit it too right, resize the entire part by 0.5% or so.

Notes

• The author of Sprinkle also includes a screen cover that is compatible with the case. Unfortunately, you'll have to remove the 3D printed screen cover (if you're using it) to charge. I tried to make the design of this dock compatible with the screen cover but some dimensional details make it incompatible with this style of dock.

• I'm also including a step file is you want to play around with the design.

• The dock is very lightweight. You may want to use rubber feet or double-sided tape to keep it in place in your desk.

• My thanks to Light-years layers for his awesome Sprinkle project.
