NxtCase Pro - for TCL Nxtpaper 70 Pro

NxtCase Pro – TCL NxtPaper 70 Pro (4 Versions – All-in-One)

A complete, 3D-printable case system for the TCL NxtPaper 70 Pro — designed to bridge the gap between the flimsy stock case and the bulky (and expensive) official pen case.

The goal: a solution that is robust, ergonomic, and practical for everyday use — while also being highly accessible and cost-efficient.

Since you can print it yourself, this design gives you a premium, fully integrated solution without needing to buy expensive accessories.
 

✨ Features

• Optional integrated stylus holder (new versions)
• Precisely aligned cutouts for sensors, microphones, and IR port
• Ergonomic button access via dedicated cutouts
• Fully enclosed camera bump for complete lens protection
• No wobble when placed on flat surfaces
• Ribbed side grips for improved handling and secure grip
• Air-cushioned honeycomb interior for shock absorption
• Built-in PopSocket cavity (on supported versions) for a flush fit
• Improved durability and impact resistance vs. stock case
• Clean, print-optimized geometry

Integrated Stylus Sleeve

The latest versions include a side-mounted stylus sheath, allowing you to securely store your pen directly in the case — always within reach and neatly integrated into the design.

The official TCL stylus is relatively expensive.
However, fully compatible alternatives are available for around $7–8, making this setup extremely cost-efficient.

👉 The result:
A complete pen + case solution at a fraction of the cost of the official accessories.

💡 PopSocket Compatibility (Smart Solution)

Due to the phone’s nano-textured back surface, PopSockets won’t adhere reliably on their own.

To solve this, the case includes a credit card–sized recessed cavity:

→ Insert a thin plastic card (e.g. cut-out loyalty/credit card)
→ Creates a smooth bonding surface
→ Allows secure, long-lasting PopSocket attachment
→ Keeps everything flush and neatly integrated
