Right-angle PEX bend clamp w/ mounting, 4 sizes

XL remix of my original Cable Bender. Thickened and stiffened, with 6x or 8x bend radius suitable for PEX tubing. Also features slotted and countersunk mounting tabs for securing to walls. Coiled ends make Installation quick and easy. 

Available in 4 common PEX sizes: 3/8", 1/2", 3/4", and 1" (actual OD is 1/8" larger than PEX size name).

Choosing a Bend Radius:

Use the 8x radius for PEX-B or PEX-C (the standard cheap varieties). The tighter 6x radius is only suitable for PEX-A, which is more flexible and expensive.

For the 3/4" size or larger, it's important to pre-bend the tube as much as possible before forcing into the bender! Running it under warm water or hitting it with a hair dryer will make it significantly easier and less likely to break the bender.

Material: 

Don't use PLA on hot water lines! Typical residential hot water is around 50 C which will soften PLA. Use a higher temp material such as PETG, ASA, ABS, or PA6.

How to Use:

1. Print the appropriate size bender
   1. Tap Prepare to Print then Next
   2. Tap Select parts to print
   3. Uncheck Select All on the bottom
   4. Select your PEX size and radius, and tap Confirm
   5. Scroll down to Copies in a plate and increase to the desired amount
   6. Tap Start Print
2. Hook one end of the bender onto the tube
3. Bend the tube past 90 degrees and slip into the other end, then pull straight
   1. Pro Tip: Run the tube under hot water from the faucet, or blow with a hairdryer to soften

4. Enjoy your bent PEX!

    

Other Notes:

• Please post pictures! I love seeing my designs in the wild
• If slicing yourself, use at least 3 walls and 20% infill. PEX is very hard to bend!
• Also, watch your infill pattern and direction with the thin portions, so you don't end up with voids 
  • I recommend Aligned Rectilinear with direction set perpendicular to the part.

Updates:

• 2025.03.21: In response to user feedback that one of the spiral clips snapped during installation, I have increased wall thicknesses all around, making the finished product much stiffer and less likely to break. 
• 2026.01.20: Added a 1" size! Can only be printed on a larger format printer such as an H2D.
• 2026.01.24: Significantly beefed up the 3/4" size 
• 2026.01.26: Added an experimental 45-degree 1" bender that can be printed on A1 or P1S
  • 2026.01.27: Reduced 45-degree 1" bender by 5 degrees each after testing
