MMU under shelf auto rewind spool holders

prusaprinters

This is a remix that is already a remix :-)The following changes were made to my remix:The hangers have been designed so that they can be mounted on the ceiling or wall.They can be mounted on the ceiling or on the wall.The spring element was given a snap-in function so that it can be inserted into the bobbin holder.can be inserted into the bobbin holder.I have attached a small collar to the bobbin holder toso that the bobbin does not slip down.I also provide the models as STEP to facilitate future modifications.I took most of the text here from "INeedOneDesigns"."Inspired by Vincent Groenhui's Auto Rewind Spool https://www.thingiverse.com/thing:3200204 I decided to make under shelf / hanging spool holders for these.This uses the metal rods and 608 bearings from the Prusa MMU spool holder.I added a square end stop to the spring design by Vincent Groenhuis and then made some hangers for them."The hangers are printed flat so they are easy to print.Material:The feather should definitely be printed with PETG.The rest can be made from PLA.To assemble the coil, push a metal rod through the spring into the square end stop; this is a very tight fit so make sure you push it all the way in.Slide a 608 bearing into each side of the wide hub.The spool hub and spring will slide into each other and lock into place, rather than just being two flat pieces glued together. On mine they fitted tightly and I didn't need glue for the new parts. If they are still too loose, just put some glue on the rim.Once they are glued together, you can slide the round coil end cap to the other side to hold everything together. To make sure the final length of the whole shaft, including the end stops, is 22-23mm, slide it all the way on.Please note: that the spool holder should still rotate slightly to ensure function.The PTFE tube attachment should be positioned centrally to the bobbin holder. if you want to keep me awake, feel free to buy me a coffee ;-) https://paypal.me/saiboTTech
