Prusa MK4/MK4S tool holder

This is a tool holder for Prusa MK4/MK4S.

It can hold all tools comming with MK4 kits :

• All hex and torx keys
• Pliers
• Screwdriver
• 2 universal wrenches

It has also extra spaces for more tools :

• A rectangle hole at the end (designed to hold a caliper)
• A hook (design to hold a scraper, the one in the pictures is Hex Scrapper II from @MattBoyer)
• A rectangle bin at the top of the power supply block (I store my glue here but you have enough room for something else)
• An extra hole for one more small tool (I store a dremel metal scraper for nozzle cleaning)

It stays in place with two hooks on the frame and 2 deadstops on powersupply. I made the toolholder protrude enough to prevent the tools from touching the powersupply. To install the toolholder, hook it on the frame the same way you do for the original prusa spoolholder. Do it higher than the top of powersupply to have enough clearance for the deadstops. When it's hooked, just slide it down on the powersupply. 

Having all these tools here does not seem to interfere with input shaping (alpha firmware 5.0.0) : everything is working well.

Technically the toolholder is outside of printing area so the extruder will not touch it during printing even next to it. But collision is possible if you calibrate X axis when the extruder cables ziptie are at the exact height of the toolholder. (It will touch the hook for the frame.) That is basically never happen, so not an issue for me.

Designed for PLA printing, but I'm sure it's also ok with PETG.
