    We have a thin strip of mint that’s exactly what you described. Fresh mint all spring and summer is great for a variety of reasons, plus it smells good. That said, we’re constantly fighting runners trying to grow in every conceivable crevice. It tries to grow in the cement expansion joints and in the joint between our house and sidewalk by the door.




  • It’s normal

    This is disappointing. Not because it’s normal, but because so many photos of prints you see on the web extolling print quality are in ideal lighting. It’s misleading at best. I will say surface quality is oodles ahead of my old I3 clone, but this has always miffed me.

    I think it’s more visible the thicker your layers are

    I do tend to print in chunkier layers. Also thicker extrusions and nozzles…

    If you’re printing with ASA, perhaps you could use some light acetone smoothing

    It doesn’t really bother me as my prints are functional, but there’s always been this nagging thing in the back of my head regarding surface quality relative to what folks on the internet present they achieve. The photo in this post is guilty of this TBH. The print looks way worse on the bed thanks to a taller printer with top mounted lights resulting in a steep lighting angle relative to vertical surfaces. It’s like going on a picturesque trip only to find out that all the photos you’ve seen online take a lot of liberty with timing (ie super early/late in the day) and/or framing.




  • 2.4 R2 owner chiming in. I built mine about 3 years ago after window shopping for a year.

    Why Voron in 2026?

    • They’re fully open source. This has a couple of benefits such as (basically) guaranteed repairability in the future and super easy modability. Basically all the parts are standard, so you should have no problem sourcing replacements. Want to change something? Download the official CAD and remix
    • Being open source means there’s a huge quantity of official and unofficial mods available, as well as tons and tons and tons (and tons and tons, but I’m getting tired of digging up links) of commercial hard parts if you want to tinker. Yes, commercial printers also have mods available, and even some hard part swaps, but Voron is next level if you like to tinker. Even if you don’t like to tinker, some mods are fantastic from a quality of life perspective and of course there are many many vendors that will sell you kitted parts
    • The printer itself is highly capable in ways that go beyond just being CoreXY. Both the 2.4 and Trident can mechanically get their bed and gantry in plane because they use multiple z-steppers to move the bed (trident) or gantry (2.4) up/down. Bambu’s printers use a single stepper and a belt to connect things
    • Even if you buy a BOM in the box you’ll learn a ton building the printer

    Why not Voron?

    • No official store or kit means you’re going to either rabbit hole who to buy a BOM-in-a-box from or spend a lot of time self sourcing. I personally went with West3D’s configurator
    • You’re building a printer from literal nuts, bolts, linear rails, and extrusions. It’s not a hard build, but it is a long build. If you can put together IKEA furniture you can build a Voron, but it’s going to take 20-40 hours
    • They’re not the budget proposition they once were
    • You’ll spend more time thinking through the build up front (who to buy from, what components to swap, what out of the gate mods, etc). Easy example: want to tune for resonance compensation? Gotta mount/wire up an accelerometer on the toolhead, unless you use one of the many tool-head PCBs that include one
    • Cable chains look dope, but wire breaks are real. They’re easy to repair, but they’re annoying. Granted, you can just go umbilical out the gate. LDO’s Nitehawk SB is dope
    • You want to go even bigger. You can stretch a Voron taller, but Rat Rigs go quite a bit bigger

    Edit: final thought. IMO I do not find myself wanting for “tech” and there’s really not much missing from a Voron out of the gate. Nearly anything a Bambu can do is easily adopted to a Voron if you want to.

    Self designed very specific objects are where it’s at regarding 3D Printing IMO. Once you get into the habit of realizing that you can print a part for <x> you’ll find yourself doing it again and again.

    Examples I’ve designed and printed include:

    • two bluetooth speakers. I’m getting ready to print my first subwoofer
    • tons of replacement parts (parts for kids toys, replacement knobs for our stove as the oem ones are $50/pop, etc)
    • wheels with TPU tread and pockets for bearings for a fold up wagon. We’ve used that to cart our two kids around for 3 years now

    You also find yourself being more adventurous with modifying other things knowing you can print interface parts. For example, our outdoor table had a 1.5" hole for umbrellas. We wanted a larger umbrella, which requires a bigger hole, so I cut a portion of the metal center of the table out and made a plastic adapter. I’ve also done lampshades and a bunch of other odds/ends around the house.



  • In my experience, broken tree branches come from:

    • Crazy angles on the supports. This happens when a support needs to ‘grow’ over the print in order reach the thing it needs to support. This ultimately comes down to part geometry, so there’s not a ton you can do here if you can’t change the geometry or orientation of the part
    • Poor bed adhesion causing the trunk to separate from the bed. Clean your bed with dish soap and dry it with paper towels. Make sure you have a good first layer by getting your your bed and gantry in parallel planes and double check your z-offset. Bonus points if you can do a bed mesh between prints
    • The extruder catching on a branch and breaking it off. This is usually due warping or over-extrusion. Warping can be its own rabbit hole. Over-extrusion is easy to tune for, especially if your slicer has built in calibration aids (eg OrcaSlicer, SuperSlicer, etc)
    • An ambitious slicer not making the supports themselves very strong. Slicers these days seem to avoid thin/tall trees, but they’re still usually single perimeter. I’ve configured my slicer to use 0.6mm thick walls on supports
    • If you have a bed slinger, tall supports can wobble. Slowing down acceleration/jerk is really the only way to combat this

    Obviously, these can all be a bit interrelated.

    The support in this print is basically vertical (no crazy angles), I generally have great bed adhesion/my printer can mechanically make its gantry in plane with the bed/I run a bed mesh every print/I use klipper_z_calibration to get a consistent first layer, nothing’s warping and I’ve tuned my extrusion multiplier for this spool of filament, the support itself is strong due to its girth at the base and wall thickness, and CoreXY means that the support doesn’t really move unless the extruder is dragging some.


  • I agree. In fact, that’s what I tend to do - slice up a design by splitting the body/bodies and printing test pieces where tolerances matter. Things like latches, hinges, pieces that have to fit with one another, etc. I’m not sure how practical this approach would have been for this print due to its final orientation, but it’s a really good practice.

    I think I got a bit too comfortable with things going per plan over my last batch of designs :( I’ll also admit to being in a bit of a time crunch. No deadline, but I have younger kids so time to model and print is somewhat limited. This is a good reminder that rushing can actually make things take longer in the end.

    Massaging this print to fit wasn’t practical. Despite being off by 1% that’s still 2mm of material to remove over some pretty big spans. I did take a chisel to the cutout, but man is ASA tough. PETG is much easier to do that with lol.

    Thanks re: print looks great. It’s super solid, so I’m very happy in that regard. I don’t know about you, but lighting greatly impacts how the surface quality of my prints look. Hard/direct light at a steep vertical angle makes the faces look pretty rough, but more diffuse light coming from the side makes the parts look great. I am not sure if this is normal, especially for a larger CoreXY with long 6mm wide a/b belts, or if this is something I can dig into and improve.





  • My hobby space is largely in my basement. I have a 27" US General (Harbor Freight) roller cab + topper that stores a lot of my tools with the exception of tools I use for automotive work. Those live in my garage in a second topper. You’ll never be able to beat the density of a toolbox and the drawers really help with organization (the hammer drawer, the measuring drawer, the pliers and what not drawer, the cordless tools drawer, etc).

    I have a partial wood shop in my basement that includes a DIY work bench. It has a number of large (24" x 30") pull out shelves in the middle for hand tools. Pull out shelves are amazing.

    My printer lives on top of two stacked IKEA LACK tables. From a concept perspective, it’s nice. It gives a space under the first table and a shelf for printer things like filament, a dehydrator, etc. In reality, the stacked LACKs are super wobbly and more tightly spaced shelves would be more practical. I want to add pull out shelves to it, which should help give it more rigidity, but I might just build a printer stand from scratch.

    So basically… pull out storage that stacks is great.
