This is a v-shaped bicycle accessory bar. There are plenty of t-shaped accessory bars but they did not have the ability to house my light, iPhone and HD-Camera at the same time. The design is optimised so as not to require supports and it is as solid as a rock even with 10% infill. Very little vibration.
Requires two 3/16" x 50mm bold and nut to hold together
I designed on tinkerCad and the resultant STL has been run through NetFabb.
ReplicatorG used for slicing with following settings:
Supports - None
Object infill - 10%
Layer hight - 0.34
Number of shells - 2
Feedrate - 40
Travel rate - 56
Print temperature - 230
Printed on Makerbot Replictor 2. Make sure you have sandpapered the plate so it sticks like glue.
