SpeedDrive documentation PROJECT MOVED TO GITHUB. VISIT GITHUB REPO FOR LATEST FILES AND UPDATES. The motivation behind creating the SpeedDrive mount was to extract maximum performance out of my ender3 with mostly stock parts. Print FAST with near-perfect quality. After pushing Bowden to its limit, I came to the conclusion (like many others), that sharp and accurate corners are simply impossible with a Bowden setup. Bowden setups are great for models with curvature, but for my particular uses, I was printing precisely engineered parts that often needed to fit together. Bowden setups produce poor corners because of imprecise linear/pressure advance due to play and friction inside the Bowden tube. This can be reduced to some extent, but never entirely eliminated.I started playing around with various mount designs and found them to be inadequate. The corners were good, but ringing and vibration prevented high speed printing and good bed adhesion. The orientation of the motor and distance from the X extrusion was not suited for sufficient inertial dampening. In creating this mount, there were two operating principles:Orientation of the motor (shaft) should be perpendicular to the X extrusion for good absorption of rotational inertia. The motor's centre of mass should be as close as possible to the middle of the X extrusion for absorption of its significant linear inertia at speed. Staying true to the operating principles, my solution was to mount the motor from behind the carriage with the extruder facing forwards. Speeds upwards of 100mm/s and accelerations of 3000+ are not only possible, these are real operating speeds that I have been using day to day for all my prints (see image of xyz cube). By no means is your printer guaranteed to get these results right off the bat, start at 1500accel and work up from there. There are now several designs and remixes claiming to be an improvement over the original SpeedDrive. I am all for innovation, however many of these designs violate one or both of the operating principles inherent to the SpeedDrive design. For this reason, I would not recommend any design or remix not explicitly listed on this page. Remixes and improvements are welcome however I encourage designers to stay faithful to the design principles. IMPORTANT NOTE!!The only downside to this solution is that the stock motor will slam into the frame unless the X endstop is adjusted. Therefore, I have also designed a 7.5mm endstop spacer that fits onto the carriage. This will shorten the bed in the X orientation by roughly 1cm on each side. In slicer, your Ender's bed size should also be changed to 200mm in the X direction.See the remix by dascook for reclaiming lost X space if thats important to you (BMG only, pancake stepper required).Also, for very tall prints you will need to extend the e-motor cable and adjust the printer's Z height in slicer to 200mm. DEMOThis is a demo of a near-perfect calibration cube printed in 13minutes using Klipper firmware and pressure advance (see picture). When my ender was still Bowden, I could only manage a 15minute cube with acceptable results. I don't know what to make of this because in theory, the Bowden setup should get higher speeds but it appears that superior corner performance and placement of the SpeedDrive negates the weight disadvantage. This is actually not that surprising because PRUSA printers are known to print at these speeds with similar quality. SPEEDDRIVE PRINT AND INSTALLATIONPrint with the flat part down, at least 4 walls and 50% gyroid infill. Enable support roof. 0.2 should be fine. PLA is fine. I recommend tightening the mount first without the v-wheel sleeves. This will

Edit 04/29/19: Added a 25 slot version per request.Was tired of having all my filament sample cards connected to a zip tie. This way I can pull one out at a time very easy and not have to worry about dropping them all while doing so. Prints all one piece, but does take awhile.Took me about 10 hours. Pretty sure the gcode thins all the thin divider walls count as perimiters, so that might be the reason. Came out great though! Allows me to seperate by color and filament type and gives me an excuse to buy more rolls to sample!Here is a link to my current design of sample cards I am using: https://www.thingiverse.com/thing:3268077

This is a convention badge and card holder I designed, inspired by the movie The Fifth Element. It is designed to be worn around the neck and contains an internal cavity to store a wallet-sized card such as a credit card or hotel room key card. The design incorporates two internal springs to make retaining and ejecting the card easy.I have included a file of the unit completely assembled for reference, however each of the included parts should be printed separately and carefully glued together to ensure that the card holder mechanism works properly.I have also included an ID template that you can use to customize and print your own IDs. It can be edited in inkscape or any vector image editor that supports .svg files.EDIT: Thingiverse doesn't allow .svg files; a copy of the ID template is available at https://www.youmagine.com/designs/fifth-element-multipass-convention-badge-card-holder#documentsA youtube video showing how the card holder feature works is available below:https://www.youtube.com/watch?v=ZWHuZMWwYi4
