Bicycle mainteance stem holder

This is a bike-specific tool to hold stem&handlebar when you service a fork or a headset. It is inspired by kLAMYnaKOLE design and feathures column for stem and spacers, tray for topcap, bolts and other small parts and holder for three 1/4" sqare bit/socket. You need some rubber or foam sheet for padding and two 25-mm TPU or nylon straps for mounting. I use PETG and 6 walls, PLA and 6 walls probably work better. Supports needed only for V-shape cutout in base, no supports in strap slots!
