UMSS - For Prusa Mk4 Spare Parts

Disclaimer: These and other models are available to all "my club" members starting at $5 per month, as well as for one-time purchase. Your support helps sustain the development efforts and the acquisition of modules. Thank you very much!

Introduction

These modules are part of the UMSS project. The project should therefore start there, with the creation and integration of tiles, eventually creating boxes and other items. These "containers" will hold these modules, which serve various purposes. In this case, they are spare parts for the Prusa Mk4 printer, but not exclusively.

First and foremost, it is important to clarify that the box with the 150x150mm tile. that you will find at UMSS - Universal Modular Storage System is merely an example. You are free to use it as you see fit; for instance, you can use multiple 150x150mm boxes to store several duplicates of the same piece, or you can use a larger box by utilizing composite tiles, like the 210x180 tile that allow you to use almost all the space you have on the build plate of your mk4, 3 and 2 series printer.

Printing

• You will find that some parts may be disabled on Prusa Slicer, does are alternatives variations on tolerances regarding the magnets, for more information please refere to the base project 
• Some parte have pauses to insert the magnets during print process. After inserting it be sure of the correct side, on all cases magnets should be attracted by each other.
  •  The Prusa Extruder is not magnetic; however, if there is any concern that the magnet may not remain secure and could potentially dislodge and strike the extruder or another component, it is advisable to apply a small amount of glue to the magnet. The same adhesive (UHU Stick) used on the print bed should suffice for this purpose.
• All labels should be printed with the smallest nozzle you have, the best will be the 0,25mm
