Roughly 8.5" tall, and 11" long when assembled.
All parts just press fit.
Features a geared mechanism to hoist the guide back and forth. Plus, a ratcheting pulley to prevent the part from slipping down.
All parts are designed to be printed without supports.
This hook made by Snorri would work great as the grabber.
1 rubber band for the ratcheting pulley.
Some small string for the gantry, and crane.
A magnet to grab things.
Not strictly needed, but an 8mm drill bit for cleaning out the mating pin holes on the frame will make inserting the pins much easier.
