    I know, I've researched that a bit and even with that the recycled filament is not without air gaps, impurities, etc. Scraping it on Recycle Days seems the best thing, then I can quit thinking about it. We tried, huh. Just seems a bit wasteful even though a new roll is less than $25. LOL

    I wish I could find one of those filament recycling machines for cheap, but otherwise right now mine go to the scrap heap.

    Hey 3DP Gang, General Question: Has anyone found a purpose for all their scrap prints? Recycle, Give Away, Toss It? Best, LB

I might recommend you go ahead download the Prusa Slicer PE program for your computer from Prusa and some of the STL files in these forums and get familiar with the options available in the Slicer PE program. It is amazing the differences in print quality by adding or deleting "supports" or which 'face' you place on the printer bed. You might also check out any of the primer videos by Prusa, if you have not already. I refer to those still when trying to improve print quality. Did you purchase the kit version or fully built version. I have used HatchBox PETG and like it for any print that needs strength or is exposed to excessive heat. I use HatchBox PLA mostly and their ABS as well with great results. Best, Steve
    Thank you Steve! That is great information. I have watched Prusa's videos and they have been very helpful. I haven't downloaded the Prusa Slicer program yet, but I will do that today to begin learning more about it.

    It appears the Prusa Mini is sold only as kit (in a way, but requires minimal assembly), but it bolts together with three primary pieces from what I understand from the videos online.

    The ETA is mid June for any current orders, so it definitely seems like they are very backed up on orders. I don't mind too much as long as it's not much longer, but a little added delay hopefully helps them sort issues (which there have been some judging by ownere posts on the Prusa forums and YouTube video reviews) before I get mine.

    I ended up purchasing a Prusa Mini. It's going through some growing pains as I expected with a new release, so I waited until I'd be in the order que that took several months before shipping to provide them time to fix any "new product blues". Ha-ha. With it, I ordered two filaments of Prusament PETG, which seems like a decent all around versatile filament type without too much trouble printing and no need for an enclosure, yet rather resilient. You all know much more than I do about that though from experience, so I'm all ears.

    T-CAT, Which 3DP printer did you decide to buy?

    Alrightttttttttttt, my first 3D Printer has been ordered. Now for the lovely wait to be delivered. I'm looking forward to digging into it and learning more. I love stuff like this, so I'll be having a lot of fun.

    I may build the nonfpv version as well in different material. For testing purposes

    Its what's called a black wing ebw160, I bought the plans and files for this one to rejuvenate my n9mb project. It is weird to fly but suprising smooth too.

    rifleman_btx, Amazing looking airframe and forgive my ignorance but it's like something out of Germany's WW2 R&D section or an Indiana Jones movie. No vertical. Outstanding. Best, LB

    DM, Hey how's your cockpit build going? Pictures? I will post STL Files of the vents, etc when I get back to the fuselage and "correct the sizing". Right now I'm working on painting and lighting the Vertical Stabilizers. I received my graphics from Callie and those are great, so lots to do. Best, LB

    Just need to run some airfoil analysis to decide on a wing airfoil before I dive in. Thinking between the Clark YM-15, NACA 2415, and NACA 3712 (close to scale)

    here is the download, the designer also has a salamander for a 120mm EDF:

    You really do amazing things!! Glad you are local and I can sponge off all this greatness in person!! and YES Jet Jam will ROCK!

    EDIT - 24.04.2026 Added an exploded view of the outer removable wing panels. Always dry fit everything before gluing. Carbon tubes should seat all the way in. EDIT - 29.08.2023 I added a reinforcement block (WingReinforcement.stl) for the inner wing panel that increases the torsional rigidity of the wing by preventing deformation of a weak spot under landing loads. Install according to the illustration. I also added a new impeller for the EDF that sounds great and might give a slight performance improvement (Gleich-Impeller07-12b-fat-Newblade.stl). EDIT - 20.05.2022: New EDF impeller with 18 blades. It sounds much better and performs well. Flight video: https://youtu.be/XvHo3N9S8D0 EDIT - 20.09.2021: New front nose piece with clamshell hatch for making access to a battery or whatever you want to put in the nose. Use an M3 screw to hold it closed. EDIT -22.07.2021: Added a new EDF housing that can use the HET motor without any heatsink because the heat sink can be hard to find now. EDF-housing04-Noheatsink.stl It supports the motor all the way through and has a gap for air to pass around the motor. It should be printed from a more heat resistant material than PLA, and that goes for the impeller as well because the lack of an extra heatsink can raise the motor and axle temperature to where the PLA will start to soften. EDIT: Added a new canopy that is one main piece instead of two for printing in a very large printer (in addition to the front windshield part). The new files are Canopy01-onepiece and canopy02-onepiece. The human is not included. Specifications: Length: 1858,5 mm Wingspan: 1451 mm All up weight: 7,2 kg (prototype #1), 8 kg (prototype #2), 7,5 kg (prototype #3) CG: 83-103 mm from the leading edge at the wing joint with the gear in the up position. There is a protrusion on the top of each wing surface to indicate the safe 83mm/25% MAC position. Gear up or down should make little difference because of the low weight of the nose gear. The prototype maidened with CG at approximately 90 mm. 103 mm CG has been tested and flies very well. Needs a large printer. 300x300x300 is recommended. Initial control throws: Elevator: Up 18 mm / Down 16 mm Ailerons: Up 20 mm / Down 15 mm Rudder: 15mm / 15 mm Use 30% exponential on all surfaces to reduce center sensitivity.
