Ender 3 V3 SE attached tool holder

This is my first 3D modeling project, so apologies for any rough edges so to speak. 

I like having my tools easily-accessible, so I was lucky I found PTJim's tool holder for the Ender 3 style of printers. Designed to hold the set of starter tools that come with the printers, these holders mount to the top of the printer using the existing holes for holding together the gantry, meaning that the printer doesn't have to be modified to use these. 

I liked the general idea of having all your most-needed tools within easy reach, but I wanted to reorganize the features he had included (i.e. the mounting holes for the tools he wanted to prioritize). I took the approach of "more is better" and just added locations for all the tools I'd want to use at any point, though there is some overlap between them. 

The left side has locations to hold:

• A hook (to which I mount my metal scraper)

• Locations for a glue stick (the thicker kind, I personally got these 22g Elmer ones; non-affiliate link)

• Deburring tool

• L wrenches

• Hex keys

• Screwdriver (YMMV with which one you decide to put there, I made it to fit my Klein multi-bit model)

• 0.4mm declogging needle (could probably fit a larger diameter, but those are the ones I have)

• 5-in-1 nozzle spanner wrench (though you can see I improvised to hold some tweezers)

The right side has locations to hold:

• Filament cutter

• Needle plier

• 0.4mm declogging needle (same as above)

• Calipers

• 3 nozzles

• Xacto knife

• 5-in-1 spanner wrench

• Tweezers

• 2 x brushes (one brass and one plastic; these are specific to the ones I have so they might not suit your needs, so import the STL/STEP into your CAD software of choice and change the dimensions by extruding the faces to cut them bigger)

• Clog poke

• Plastic bed scraper (specifically this one from MakerWorld, though I don't quite like it to be honest as changing the blades is hard)

• A hook (to which I mount my ruler)

To mount these to the printer you'll need:

• (6) M3x20mm screws (3 per side)

• (6) M3 washers (3 per side; optional but recommended)

Don't screw down too hard to avoid putting unnecessary stress on the surface. 

This is entirely tinkered to fit what I want, and it was the model I used to start learning Fusion so it's not perfect, but it gets the job done and so far I've had no issues. 

Printed in PLA Pro/Plus, 25% gyroid infill (though honeycomb, cubic or grid can also work), 0.2mm layer height, 0.4mm nozzle. Print with the top facing the print bed to avoid the most supports and ensure the curvature of the gantry-mount remains accurate. Supports will be needed and they'll generate for the hooks and the other holes that don't go all the way through the model. 

Might revisit this in the future and make some more adjustments after using it for some time and after learning a bit more about modeling and 3D printing. Hope you find it useful!
