Prusa LACK Enclosure External LCD Mount (MK2/MK3)

A mount for installing a Prusa i3 LCD controller on the outside of a LACK enclosure. Compatible with MK2 and MK3 LCD assemblies.  Not compatible with MK4 LCD assembly.

Description

This is a redesign of zamky's Prusa i3 LCD Holder that features the following improvements:

• Relaxed part tolerances for easier assembly
• More robust ribbon cable channel
• Option to attach LCD to mount with M3x10 screws
• LCD support pieces based off of MK3 printed parts (still MK2/S compatible)

Installation

The mount is intended to be installed on the front edge of the lower LACK table, just below the doors. The bottom edge of the mounting bracket should be flush with the bottom edge of the table to ensure adequate clearance between the bottom of the doors and the top of the LCD controller assembly.

If desired, the LCD controller can be secured in the mount by using two M3x10 screws in the holes provided on either side of the bracket. (If you removed the LCD assembly from the front of an MK3, you should have four M3x10 screws left over.)

A passthrough tube large enough to route the LCD ribbon cables to the underside of the table is available here:

Print instructions

The Gcode file is sliced for Prusament PETG on an MK3/S using the 0.20mm QUALITY MK3 setting. I used 10% infill, and all other settings were left at defaults.

3mf files have been provided for those who want to do the slicing themselves.
