What Have I Been 3D Printing?


What Have I Been 3D Printing?

At this time I used to be supposed to be writing a evaluate of a LED mild that matches into the Ender 3’s body and illuminates the print mattress, however I can’t, as a result of it doesn’t work. I suppose as opinions go that’s all it is advisable hear, truly, but it surely’s a bit on the brief facet, so I assumed I’d discuss a few my 3D printing initiatives as a substitute.

Filament Drying Helper

I’ve talked about earlier than that I take advantage of my kitchen dehydrator for drying filament that’s been not noted too lengthy. Not too long ago I’ve been a bit lazy about resealing filament that I haven’t been utilizing, so this week I discovered myself with half a dozen spools which have in all probability picked up extra moisture than was good for them. Sadly, that was a problem for the dehydrator. It pumps out heat air from a raised round vent within the centre of the mattress; one spool of filament sits on high of that fairly properly, but when I attempt to stability two or extra on there they have an inclination to fall off. As I shortly found, the toppling spools will both dislodge or tear the bin liner I take advantage of as a canopy when drying filament.

Fortunately this was simply solved. I opened FreeCAD and designed a easy 150mm large, 50mm excessive help ring that sits around the air vent. I lower out holes round it to let heat air flow into, then printed one off. Now I can dry an entire stack of spools without delay.

Desk Organiser Mount

With my filament all dehydrated and vacuum-sealed, I made a decision to deal with a extra sophisticated venture. I hate having a messy desk, however I additionally hate having to rummage in a drawer each time I desire a pen or another small however helpful factor. To get round this I purchased myself a desk organiser, which I figured would maintain all of the small litter that builds up. Sadly I shortly bought aggravated with having it on the desk, so I made a decision to screw it to the entrance. That approach it could be in simple attain however not taking on any of my workspace.

I’ve discovered from expertise that simply screwing issues collectively doesn’t all the time work, and this appeared like a type of occasions. The organiser is product of expanded steel, and that doesn’t have an important energy to weight ratio. If I merely drilled a few holes in it, and screwed it on to the desk, there was a superb likelihood it could bend below its personal weight, and both lean below the desk or rip the screw heads out by way of the mesh. Fortunately I’ve a 3D printer, so designing and making a mounting system is straightforward.

The design I got here up with has 4 components. The primary is a mounting bar that I connected to the desk with a pair of 1.5” wooden screws. It’s lower away on the again so I can feed my tangle of USB cables down behind it, protecting them a bit tidier. Then there’s a backplate with two brackets screwed to the again. The organiser’s weight can’t swing it backwards, as a result of the brackets push towards the underside of the desk. Lastly I drilled two holes behind the organiser, and used two M3x25mm screws fitted with washers to lock that and the backplate to the mounting bar. The tip result’s a pleasant tidy mount, with solely two of its eight screw heads seen, and it’s just about rock stable.

One other Ender Improve!

My subsequent venture is one other improve to the Ender 3 itself. Just a few weeks in the past I fitted a filament break sensor, which is a really useful little gadget, however its mounting system isn’t very best. It’s screwed to a really substantial metal bracket that mounts in totally the incorrect place on the printer. It’s designed for a 3D printer with a normal extruder and Bowden tube setup, however our Ender is direct drive and the extruder is on the Y axis beam. It’s potential to feed the filament spherical an extended and tortuous path that takes it by way of the sensor, across the body and as much as the extruder, however this appears a bit daft. In addition to making the extruder work lots more durable than it must, having the filament flip by way of two proper angles then come up from beneath a top-fed extruder in all probability makes it ten occasions extra prone to break.

What I wish to do is detach the sensor from its bracket, then design and print a brand new mount that may place it immediately above the extruder. That provides a pleasant brief feed path, straight down from the spool and into the highest of the extruder. I’m additionally planning on changing the extruder and scorching finish, that are at the moment linked by an inch of Bowden tube that’s a whole ache to switch, with an all-in-one unit; as quickly as that arrives I’ll determine the way to get the sensor mounted, and little question you’ll get to examine it right here.
