Modular Bed Mount - E-Reader, Phone, Tablet

Simple design, fully adaptable, easy to print
No supports required

This fully adaptive bed holder is designed to securely hold e-book readers and tablets while allowing comfortable, hands-free reading in bed.
The construction focuses on flexibility, stability, and ease of printing, while remaining modular and customizable.

*Update 28.07.26:

• added 25mm (user wish)
• added adapter on second print plate to connect the rod with the 4 feed

Idea

The idea was to create a fully adaptable, modular bed-mounted holder that:

• can be printed without supports
• is easy to assemble
• allows hands-free reading
• works with different devices and bed setups
• does not require permanent installation or damage to furniture

The design prioritizes comfort, adjustability, and simplicity while remaining sturdy enough for daily use.

Modular Components

Device Holders

• 6 sizes from 9 to 14 mm (delete or remove the ones you don’t need)
• Recommended: measure your e-book reader and add +1 mm
• Connected to the different systems using a ball joint, which can be secured at multiple angles

Base

• Simple 4-feet stand with an insert for the ball joint

Extension Rod

• Fully adjustable rods in different size ranges:
  • 50–106 mm
  • 90–185 mm
  • 118–257 mm
  • 158–346 mm
• Friction-based locking (no tools required during use)

Measuring tips:

• When using the bed frame clamp, measure from the top of your bed frame border to the top of the mattress
• When using the mattress insert for borderless beds, measure the height of the mattress
• If the final height still doesn’t fit, you can print a separate adapter (included in the print files)

Bed frame clamp

• Adjustable Clamp from 10-27mm (you can ask if you need more)
• The locking screw has a snapfit head, just push it inside the head

Mattress insert for frame less bed

• Inserted under the mattress with adaptable hirth joint in 10° steps
• The adapter adds an height of 47mm, so keep that in mind when choosing the rod
• Also locking screw has a snapfit head, just push it inside the head

Separate adapter

• a Small joint to connect to the top of the rod
• Adapter in different sizes:
  • 20 mm
  • 40 mm
  • 60 mm
  • 80 mm

Building instructions

In the pictures gallery there are drawings how to assemble each unit. 

Print Settings

• I used PLA for the majority of parts
• I recommend printing on a high-temperature smooth build plate, especially for the extendable rods, to ensure a perfect fit
  • I also tested the textured plate, but connecting the rod parts is more difficult on the first attempt
• For the clamp, I recommend PETG, as it does not lose its original shape over time
  • PLA also works
• Layer height:
  • 0.16 mm in my printing profile
  • Use this at least for the ball joints and extension rods
