Work in Progress: Uploading Current Version of Attempt to Save $25-30 per Servo for Aluminium Parts on Amazon etc. **The Shaft May or May Not Work Out for You; I Had Best Results Printing at a Weird Slanted Angle with PETG and an M3 Set Screw Shoved Down into It, but Even Then I'm Not Happy with the Strength. If You Put Any Force on It and Have Printed the Shafts in the Easiest Way (Vertically), It WILL Eventually Fail.** I Will Update with a More Refined Version of This Experiment, but Here's What I've Got So Far: I Recommend 80% Infill, PETG Only, and Using a Drill Bit to Get the Holes Just Right During Assembly. You'll Need a 608 Bearing for the Part Labeled as Such; I Used a Vice to Press the Part in. The Tolerance is Pretty Tight, so Plan on Forcing It in or Printing with the Bearing in After a Few Layers If You Want to Get Creative. Again, Totally a Work in Progress: Only Failures Were with the Shaft in All Kinds of Stress Tests, So If Someone Finds a Nifty Way to Get That Thing to Hold Up After a While, Please Remix and Let Me Know! **Non-3D-Printed Parts Needed:** -- 1x 608 Bearing (I've Been Using Very Cheap Ones I Salvaged from Fidget Spinners I Found a Good Deal On) -- 4x Aluminium Screws - I'm Guessing These Are 0.5 mm Dia, but to Be Honest I Just Used What I Had Lying Around and Used a Hacksaw to Cut Off the Ends to Size After Screwing in -- 4x Nuts to Accompany the 4x Screws -- Some Sort of Screw or Bolt to Hold the Servo Body to the Plate; I've Found That It Holds Up Fine with Just a Couple Zip-Ties to Be Honest **Update 7-10-2019:** The Horn/Arm Will Last Longer If You Print It Horizontally, but I've Since Scrapped the Whole 608 Bearing for that Particular Portion by Gutting the Bearing Itself and Keeping the Outer Ring.
