Turn 488 Challenge DIY Sim Racing Wheel for small bed printers
Description
UPDATE: I had a request, and feel dumb for not thinking of it, but they wanted a version of the enclosure with clipped ears, but leave the center 70mm mounting lug holes even with the top so you can still print the backing but order a carbon fiber front plate and not worry about sandwiching a 3D printed face plate. Please let me know of any other modifications you need made and I will try me best to accommodate them. JB Remixed from: https://www.thingiverse.com/thing:5168404 I am working with TURN Racing https://www.turnracing.com to convert these awesome DIY projects so they may be printed on small 220mm print beds. I had to take some liberties with the original designs in order for the conversion to safely function on the strongest Direct Drive Wheels. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// A zip file is included in the file section for download which contains the entire package. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// I modified the original to allow printing on an Ender 3 Pro 220mm size build plate. The main Plate is sliced in the center. Using 2 caps, the main plate is then laminated to become one strong part. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// https://www.youtube.com/watch?v=RO-L_dRdLXo&t=55s ////////////////////////////////////////////////////////////////////////////////////////////////////////////// Using Turn 488_Challenge_220mm_Print_Bed_Front_Plate_Top_Cap and the Turn 488_Challenge_220mm_Print_Bed_Bottom_Cap, Sandwich the 2 main plates. On each side of these 4 parts, are 4-5mm holes located to the outside of the 6 Wheel mounting holes. Yes I added the 2 missing mounting points to increase strength. Using 8 5mm Button screws, sandwich and tighten the 4 parts. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// At this point the wheel can be used without the Electronics box, for say an old G27, or myself where my button plate is mounted to the wheel and just the wheel has the quick connect... ANYWAY... ////////////////////////////////////////////////////////////////////////////////////////////////////////////// Now lightly squeeze the tabs on the Turn 488_Challenge_220mm_Print_Bed_Enclosure_EARS and they will snap into the Enclosure. Now you have an assembled Enclosure. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// Place the Assembled laminated wheel parts into the Enclosure. It will basically self align with the 6 5mm main wheel 70mm mounting holes. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// Now screw the parts together using the 4 - 4mm threaded holes printed into the 4 corners of the Enclosure. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// Mount the assembled wheel to a quick release or just to the main head. The 6-5mm screws for the 70mm Wheel hub attachment, will finish off the lamination and provide a strong wheel. Now attach the Grips and so on. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// I did not modify the Grips, paddles, paddle parts, or knobs in any way, I simply added them to my files for ease. ////////////////////////////////////////////////////////////////////////////////////////////////////////////// Please find me on the Turn Discord Server or at jameseburroughs@gmail.com ////////////////////////////////////////////////////////////////////////////////////////////////////////////// Thanks for supporting the DIY community. Feel free to modify as you need to fit your project. I ask that you do not sell ot make proceeds from my work. I do this for fun because I am handicapped and retired. Your Friend James Burroughs Baudette, MN ////////////////////////////////////////////////////////////////////////////////////////////////////////////// PS: I included the unmodified stl's from the rest of the project so you don't have to go back and find them.
