Samsung galaxy s3 phone holder belt clip

Do you want to use speakerphone, but are tired of holding your phone up to your face to talk so people can hear you?

Are you biking or jogging, and want your phone firmly held by your waist so it doesn't bounce around?

This is a tight belt-clip for the Samsung Galaxy S3! (the S has a restricted symbol by it). It was made online in Tinkercad, which owns Sketchup as a quick design tool! Its probably compatible with other phones, but I can not be sure. I printed mine with PLA at 220 degC, .25 mm layer height, at 40 mm/s, it took 1 hour to print in full fill on a prusa mendel.

You can clip it on your belt or the V-neck of your shirt because it is so light. Then you clip in the phone sideways (over the top may not be safe due to roughness). Be careful to not scratch your phone - see notes.

Use the included gCode or slicer config as a guide for Prusa Mendel Makergear V2 (http://www.makergear.com/products/3d-printers) with 5:1 kliment firmware as recommended by Josh on the IRC forums.

Black PLA set temps are higher (210-220C) than white PLA. Higher temps make much better 100% full fill and bind the parts STRONG so that your belt clip wont break easily. When I went below 210, the PLA would not stick to the glass. 220C was idea. Also Optimize your extrusion ratio so that you get full fill, but not so much the part warps from overfill.

Align your device very well - use glass for this design and level to <0.1mm. This is because the part is huge and flatness matters. I used a 100C base temp, which is high for PLA.

Do not scratch your phone - Smooth out edges with a quick <1 second pass with a flame end or blow torch. Cut away loose filament. Optimize your printer to retract so that on the return sequence extra filament is not deposited. I slide in my phone side ways (not from the top) and it does not scratch.

The belt clip is VERY strong. It will bend around a few MM or object, but not a very thick (>5mm) or more might cause it to bend.

In future additions, smoothing of the design and making a more sturdy and elegant holder edge are desired. If you want to make derivatives PLEASE do, just let us know so we can print one.
