Historical wrench (inspired by Hand Tool Rescue)

This is not exactly NASA wrench, but it is also easy to print and you can use it in so many different ways (see complete video below :) If you print this thing, I will be happy to see your make in "Post a make". If you find this even useful, you can buy me a Mr. Brown coffee ;-) PayPal me: paypal.me/elcarloscz BTC: bc1q6qz298fescrhxzfwknuysek4x0jzyrvy2lnnz0 ETH: 0x0b55c5DA1f22150A6DA3d0E87fB0674041F22446 LTC: ltc1qqvrng2wlc7kzv8f764372tjprt052unykv93dl XRP: rPZNYxUyLYxsHK5dr3gaDv5uzAN5fgopjg DOGE: DCz3cB8W9bgocPP2z6mcQbpuoynLmLzToy Print Settings Printer Brand: Prusa Printer: i3 MK3Rafts: No Supports: YesResolution: 0,2 mm Infill: 20% Filament: [ any PLA ](http://www.amazon.com/s?url=search-alias&field-keywords=any+PLA&tag=thingiverse09-20) Notes: See below for file-by-file guide ;-) How I Designed This I'm trying to learn with Fusion 360 and this was next challenge for me. I'm fan of HAND TOOL RESCUE YouTube channel. This guy is really amazing in restoration old tools and devices. One of his project was resurrection of historical wrench (originally patented in 1879 by Charles Billings). As he offers this resurrected mini version on , you can now also print one from your favorite plastic. Be sure to check his video how to made this wrench in "old-school" (not 3D printed) way :) How to print this Tested filaments: PLA, PET, CPE-HG100 (Fillamentum) and PC Max HOW TO PRINT Most easiest way: Put all 3 STL files in slicer, turn supports ON (from bed only), resolution between 0,1 mm and 0,2 mm, infill between 20% and 80% and hit RUN button ;-) There is 3 different parts. KNOB.stl is easies one. Just print it without supports with no higher layer than 0,2 mm. HAMMER.stl You can use supports, but it went fine also without them. Again, for thread isnt good to try something above 0,2 mm layer height. If you wish to really tight something with wrench, use higher infill, at least for part with thread. I tested PC MAX with 100% infill and it can really handle nuts and bolts. For toy/model purposes also 20% infill will work. HANDLE.stl Here you will need supports. With Slic3r PE works "only from printbed", but be sure that you get also supports in the middle, as shown on picture below Resizing Actual size is good enough for 0,4 mm nozzle, so I can't recommend downsizing, but you can make this thin even bigger. Prusa printbed can handle 190% size of original STL models, see: Category: Hand Tools
