The ball screw and nut from <a href="https://www.printables.com/model/507713-ball-screw-and-nut" rel="nofollow">my previous model</a> are integrated into the moving actuator tube. It uses 28 6mm dia. airsoft BB's for bearing balls. The stroke is 150mm. I've tested it with a short (34mm long) NEMA 17 and can get about 10kgf. The pitch of the screw is 6.5mm.Just a few additional screw parts are needed: - 5 M3 x 5mm screws - 2 M3 x 12MM screws - 2 M3 nuts - 2 M4 x 12mm screws for the base yoke - 1 M8 x 35mm bolt for the end yokePrinting I printed all parts in PLA with 0.2mm layers. The only part that might need supports is the base yoke on the inside of the big holes. When printing the screw you need a near perfect first layer and is best done on a printer with mesh bed levelling.Note that the motor end of the screw has a horizontal slit with a built-in support. Use a thin blade to remove this support.Assembly First follow the instructions <a href="https://www.printables.com/model/507713-ball-screw-and-nut" rel="nofollow">here </a>for assembling the ball screw at the end of the nut tube. Position the ball nut to the middle of the screw. Insert the nut tube into the motor tube so that the end of the screw protrudes out of the back end of the motor tube.Next, insert the motor shaft into the end of the screw, leaving about a 1.5mm gap between the end of the screw and the face of the motor. Insert M3 nuts into the clamp at the end of the screw and then insert and tighten the 2 M3 x 12mm screws.Slide the motor up to the end of the motor tube and secure with 4 of the M3 x 5mm screws. Insert the last M3 x 5mm screw into the hole in the other end of the motor tube so that it protrudes into the slot in the nut tube. This acts as a stop to keep the ball nut from running off the end of the ball screw.Finally, assemble the yokes at either end of the actuator. The base yoke uses the little stud spacers on either side that are secured with the M4 screws. The end yoke is held in place with the 8mm bolt and nut.Once assembled, the actuator should be back-drivable so that you can test the range of motion. Then just connect it up to your favorite stepper motor controller.

Protect your beer with this can cover against wasps, bugs and other co-drinking persons :)The bottom snaps onto the top of a 0,5L - 0,33L (short) - 0,33L (long) can. If you want it to work with a 0,25L can, scale both parts to 0.96.Easiest way to assemble is by gently squeezing together the circle of the bottom part and slide the top into the hinge-part.&nbsp;Check out the alphabet-version as well:<a target="_blank" href="https://makerworld.com/en/models/458456" rel="nofollow noopener">https://makerworld.com/en/models/458456</a>&nbsp;Commercial license you can get here:https://buymeacoffee.com/benoengineering/e/265720

RickBigriver's caliper holder was just what I was looking for, but I rather attach it with screws, so I modified it a bit. I also needed one for other caliper beside my other printer, that one is with smooth bottom and attached with double sided tape. Original holder was a bit too tight for my caliper, so I also widened the gap a bit. Both .stl and .3mf files included.Biltema pegboard holes are 4mm wide and 12mm abart from each other and it is sold in Scandinavia, but there are other brands around the world with same diameters.

<h2>Meet the Smoothy!</h2>The Smoothy is a PTFE Bowden Tube Y Connector designed for smooth filament transport without catching or binding. This allows you to use an external spool with your Bambu Lab machine without disconnecting your PTFE Bowden Tubes.&nbsp;PTFE tubes are inserted deep into the connector for less wear on the FDM material. This allows for silky smooth operation.&nbsp;As the filament progresses towards the output, it passes through a precisely-designed taper that mates perfectly with the output bowden tube.&nbsp;All PTFE tubes must be inserted until each “stop” is reached (see cutaway diagram).&nbsp;Connectors must be the black type (not blue). The black connectors allow the PTFE tube to “pass thru” which is required for the design to work smoothly: <a target="_blank" href="https://www.amazon.com/gp/product/B0B97RWKQR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1" rel="nofollow noopener">https://www.amazon.com/gp/product/B0B97RWKQR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1</a>&nbsp;<h2>BENEFITS:</h2><ul><li>No Supports</li><li>No Overhangs</li><li>No Brims</li><li>Optimized Geometry</li><li>Designed for FDM Printing</li><li>Smooth Operation</li><li>Supports both PC4-M6 and PC4-M10 “pass thru“ connectors</li><li>Free to Download!</li></ul><h2>UPDATES:</h2><ul><li>The Smoothy Mount is now available!
