2020 Extrusion Parts

Here's a set of useful 2020 parts I designed.

Corner Clip

Snaps on to 2020 extrusion to hold cables in the slot. Great for organizing long cable runs.

Cable Tie

Use 2 of the M4 T-Slot nuts and 2 M4x8 bolts to attach this tie to a 2020 rail. You can use two small zip ties to hold up to a 10mm cable bundle in the slot at a 90 degree angle. (the original Fusion design is parametric - I can create any size up to about 14mm upon request)

M4 T-Slot Nut

These handy t-slot nuts insert sideways and rotate to hold items to the T-slot when you tighten the M4x8 bolt. Removal is quick and easy. I use them to hold parts and trim panels on my Vulcanus Max.

Print Settings

Printer:

hand-built i3 clone

Rafts:

No

Supports:

No

Resolution:

0.15

Infill:

25%

Filament:

Hatchbox PLA, ABS, ASA

Black

Notes:

Print multiples at one time on a slower print speed to allow the filament to cool. Being small parts, printing too fast will not give good results.

I've printed them in both ABS and PLA. PLA (on BuildTak) is generally easier, as I have to use brim with ABS to get enough bed adhesion on a PEI print bed.

Post-Printing

Tap em!

M4 T-Slot Nuts

Run an M4 taphalf way the nuts from the top / out side after printing. This leaves some untapped to provide friction against the bold, which helps rotate the nut in the slot. I use a drill on a slow speed and hold the t-slot nut with a pair of pliers.

You may also need to file the nut slightly, as the fit is snug and if too tight the nut can't rotate to lock in the slot.
