I cracked the clamps on mine, so I thought I'd design a stronger mount.
Designed to use M5 screws & 8mm nuts (with a 10mm | 3/8 washer at the screw head).
Comes in all 3 pipe sizes - 23.5mm, 25mm & 25.4mm
The clamps are deeper as I'm using very smooth (chrome-like finish) 25mm anodised aluminium pipes, and needed them to get a better grip. This doesn't reduce Z travel.
Lower bracket (Z-Lower) now included.
For maximum strength, I'm using a 1 mm perimeter, and 1 mm top and bottom layer thickness (MatterControl lets you choose number of perimeters / layers or thickness in mm).
