Chain Whip Bike Tool

A bicycle chain whip handle. It's a very simple design and easy to print.

Hardware Used:
DIN 933 M5x45 Hex Bolt, Qty:3, https://www.mcmaster.com/#91280a244
DIN 934 M5 Hex nut, Qty:3, https://www.mcmaster.com/#90591A260
And some old bike chain.

Included 3 different lengths for different sized printers. (99mm, 119mm and 169mm)

I printed the 169mm long one out of PLA. (35% infill, 3mm thick walls and .17mm layer heights.) It was a 6 hour print but seems to be super strong. I've used it a few times to swap out the cogs on my single speed mountain bike. So far its holding up well. It may also be strong enough with thinner walls and larger layer heights but I don't know.
