Handlebar extension

Handlebar extension

By John Oldman

  • Designed to be attached to the bike handlbar
  • Designed to be 3D printed in two pieces
  • Requires additional hardware

This support is designed to attach a second tube to the handlebar to obtain a larger platform support bags. You'll need to print it twice and add a front tube.

Designed for 3D printing; requires no support material. It is usually a big component, so it will take some hours to print.

Note that this component requires additional hardware, namely a tube and 3 bolts for each support. To increase friction between the handlebar and the component, you can use a section of airtube between the two.

Machine The component will be designed to the chosen machine specifications =
Material Only the selected materials will be considered for the design =
PLA +2
Distance Distance between handlebar and end-tube, measured between axis. = mm
Width Thickness of the component = mm
Height Height of the component = mm
Handle d Diameter of the handlebar at the attachement point. = mm
Tube d Diameter of the end tube. = mm
Bolt d Size of the bolts used to secure the component around the handlebar = mm
Bag mass Mass of the bag attached on the end-tube. kg

Mass Component mass will not exceed this value kg
Temp min Will work down to min temperature or lower °C
Temp max Will work up to max temperature or above it °C

Nozzle d Nozzle diameter. If possible, features thickness will be chosen as a multiple of this value. = mm
Min layer t Minimum layer thickness. Smallest height which ensures good quality. = mm
Min w Minimum width which ensure a good quality print. This is the thinnest wall you can print. = mm
Min tol Minimum tolerance. The smallest value x such that a cylinder of diameter d will fit in a hole of diameter d+x. = mm
Pip tol Print-in-place tolerance: defined as Minimum tolerance, but with the cylinder printed inside the hole. = mm
Printer bed size x Size of the printing bed = mm
Printer bed size y Size of the printing bed, perpendicular to x = mm
Printer max h Maximum height for a printed part = mm
Max bridge Max length for a bridge = mm
Max overhang Max overhang angle, measured from the vertical (90 deg is horizontal). = deg

We have none! Please help or this is going to sink faster than the Titanic.
