terraPin High-Strength Winder (1/4" shaft)

Description

Ever Since My Original P6*6 3D Printed Pinhole Camera, The Weakest Links In The Film Transport Were The Spade-Shaped Winders That Press-Fit Into A Slot In The Knobs. Occasionally, The Stress Of Winding Film (Jams, Poor Fit, Curved Film Plane, Etc) Would Necessitate A Little Oomph On The Knob, And - Snap - The Winder Would Break. This Is A Huge Pain In The Neck. I Noodled On This A Lot. At First, I Explored Having The Original Part Custom-Made In A Stronger Material, But I Quickly Realized That I Could Redesign The Winder To Use A Standard Industrial Control Knob For A 1/4" (6Mm) Shaft (Or Even An Electric Guitar Knob With A Set Screw). There Is A Multitude Of Knobs That Will Work With These Winders. Note: I File/Sand The Bottom Of The Knob Smooth To Prevent It From Grinding On The Top Of The Camera. I Used Shapeways To Make The First Version And Iterated Them Several Times To Get Them Right. I Use Them On All The Cameras I Sell (I Have Different Winders For The Oskar Camera Knobs). I Adapted That Winder Design And Optimized It For Fdm Production. These Winders Come In Two Lengths (12Mm And 14Mm) For Optimal Set Screw Placement - Not Too Close To The End! They Also Have A Shape That **Requires Support**. I Hate Designing Things That Can'T Be Printed Without Support, But These Doodads Are Small Enough That The Clean-Up Only Takes A Minute. I Tried To Design My Own Support Structures, But I Couldn'T Compete With The Intelligence Of The [Slic3R](Http://Slic3R.Org/) Support Algorithm. The Winders Are Oriented On The Print Bed For Maximum Strength, And I Print Them At Fine Layer Height With Infill >70% For Lots Of Torsional Rigidity And Set Screw Bite. The Walls At The Ends Of The Overhangs Minimizes Warping And Distortion. You Might Need To Do Some Shaving With An X-Acto For A Precise And Flush Fit. These Winders Will Work With These Cameras: [Terrapin Oskar Lochkamera (Pinhole Camera)](Https://Www.Thingiverse.Com/Thing:1835844) [Terrapin Oskar Tuxedo 6X9 Lochkamera](Https://Www.Thingiverse.Com/Thing:2375808) [Terrapin Acme 6X6 (6X9, 6X4.5) Pinhole Cameras](Https://Www.Thingiverse.Com/Thing:1724928) [Terrapin Prime 6X6 Pinhole Camera](Https://Www.Thingiverse.Com/Thing:1253008) [Terrapin 2Ht Stereo Pinhole Camera](Https://Www.Thingiverse.Com/Thing:1090252) [Terrapin Kaiju 6X18 Pinhole Gamera](Https://Www.Thingiverse.Com/Thing:876457) [Terrapin, A 120 Film Pinhole Photography System](Https://Www.Thingiverse.Com/Thing:495230) [Terrapin 6X9 120 Film Pinhole Camera](Https://Www.Thingiverse.Com/Thing:577223) [Terrapin Bijou 6 X 4.5 Pinhole Camera](Https://Www.Thingiverse.Com/Thing:728157) And [Sidewinder Version](Https://Www.Thingiverse.Com/Thing:1167655) And The Original [P6*6 120 Pinhole Camera](Https://Www.Thingiverse.Com/Thing:157844) I Buy Heavy-Duty Industrial Knobs From [Mouser Electronics](Http://Www.Mouser.Com/Productdetail/Davies-Molding/1610Aa/?Qs=Sgaepimzzmuiwdvltmm01Ajigs4Kamb6Gjqcaqpusys%3D). They Aren'T Too Expensive, And The White Index Mark Comes Off With A Swipe Of Acetone Or Nail Polish Remover. If You Don'T Want To (Or Can'T) Print These Winders Yourself, You Can Buy A Pair From [Shapeways](Https://Www.Shapeways.Com/Product/Rha9Ee7Yg/Terrapin-Consumer-Winder?Optionid=58035275). They Will Be Vastly Stronger Than The Original Fdm Press-Fit Winders/Knob In The Thing Files. They Have A 1/4" Shaft And They Don'T Twist Off Like The Original Design. You May Need To Trim 2-3Mm Off The Shaft If Your Knobs Aren'T Deep Enough -Use An X-Acto Blade, With Small Bites. You Can Also Get The Winders 3Dprinted In Metal By Shapeways!! They'Re Spendy, But They'Re Like Jewelry! Zombie Apocalypse Bomb-Proof. For The Oskar Lochkameras, There Is A [Similar Winder Available From Shapeways](Https://Www.Shapeways.Com/Product/89Tzaa46P/Terrapin-Oskar-Winder), With A Hex-Shaped Shaft For The Oskar Knobs. ___ **Attention** This Work Is Licensed Under The [Creative Commons - Attribution - Non-Commercial License](Http://Creativecommons.Org/Licenses/By-Nc/3.0/).
