  • Not uncommon but lots of printers on the market (especially hobbyist ones) are kits that you need to assemble. Bambu printers are pretty much remove the printer from the box, remove some brackets, tape and protective packaging before installing the build plate and spool holder and turning it on.

    I’d recommend going for the P1S if you can swing it over the P1P for the enclosure.


  • I agree with the suggestion, Bambu A1mini is the only printer in that price range I would be willing to purchase and expect for it to work properly. While there are plenty of people happy with their Creality and Sovol printers, they often end up being project printers that require a lot of tinkering to keep them running well and those that aren’t prepared for that shouldn’t buy them.

    I like to say there is two different hobbies here, if you want 3D Printing to be you hobby, then spend the money on a known reliable printer, if you want 3D Printers to be your hobby, then buy a cheap printer and get ready to tinker.

    A couple other people have recommended resin printers, which are probably better for that you want to do. But be aware that resin is pretty nasty stuff and you need to have the printer in a very well ventilated area and should wear all the recommended safety equipment. You shouldn’t get into resin printing unless you are aware of safety requirements which are often downplayed by people who own them.


  • I have a couple tips if you don’t mind.

    When sketching a line attached to a circle, using a tangent contraint will make the transition between the curve and straight smooth.

    Rather than sketching the inside wall and cutting it away, you can just do a shell/thickness command. Alternately, you can offset a sketch from the outside geometry rather than drawing all the features manually again.

    Consider how the part is made, you have two very sharp corners on the centerline where the nozzle cannot create the geometry, these areas will be rounded by default, it is better to add fillets so you control what the machine does.

    That is because the holders go around an injection molded part and you need to add draft to injection molded parts to ensure they can eject out of the mold. Every CAD software worth using will have the feature. You just model the part with straight sides and then add the drafts in a later step (before you add rounds/fillets). The features generally work by picking some references to define where the draft starts from, which direction to pull the surface, and the surfaces or edges you want to draft.

    Honestly, the parts you show are super basic. If you sat down for an hour and read documentation on the basics in Fusion360 you would be able to replicate parts of that complexity no problem.



  • The PS5 side panels would be modeled using boundary surfaces (or whatever the heck Fusion360 calls them, every CAD software calls it something slightly different). Essentially you need to model the edge shape and then various guide curves across the surface that the CAD software then will fill in with a continuous surface. That said, surface modeling is very much an advanced technique within CAD softwares, don’t be surprised if you find it incredibly frustrating to learn.

    To do this you are going to need to measure points that will allow you to create the guide curves. The least work would be 3D scanning of some sort that would create a point cloud that you can use to construct the surface, there are some phone based solutions available these days, especially if you have an Apple device. Alternately you can measure it manually, profile/contour gauges are pretty cheap (heck you could probably print one good enough), there are many ways to do it depending on the equipment and expertise you have.

    That said, for something like this, I’m doing it the lazy way. A tripod doesn’t wobble, design it with some adjustability in the legs to get it fairly level, pop on some rubber feet or double sided tape to keep it in place and move on.



  • This is unfortunately the risk of the cheaper machines. Some people claim they have no issues, but you see many posts like this one that have constant problems or have spent a bunch of money to upgrade their machines to the point where they print consistently.

    The cruel reality is that the cheaper machines are better for enthusiasts that have more knowledge and are ok with the printer being their hobby rather than printing, but they tend to be bought by people just coming into the hobby because they don’t want to invest in a reliable printer until they know whether they like it (or simply can’t afford it).

    I did the exact same thing when I bought my first printer. I had already had experience with reliable printers and am very mechanically minded, so I thought I was ok to buy one that I knew I would have to tinker with. Eventually I came to the realization that to get it to the point where it would be workable the time and money would just about buy me a Prusa instead.








  • They know that they are still cheaper than any of the other commercial packages. SolidWorks’ yearly maintenance (plus you have a higher upfront cost when you acquire it) is multiple times the F360 subscription per seat.

    They aren’t interested in dealing with low value business, the only reason they even have a free version is to get potential future customers used to the software so they demand their employers buy it over their competitors. Same reason why Dassault Systemes gives SolidWorks to students for free.
