Model Rocket Jabaketa 2 Ultima, printed nearly completely in vase mode, no support, with a case

Have also a look at our other designs. https://www.thingiverse.com/kledolin/designs

Soon other rockets are going to follow. Please comment if you are going to build the project.

Here is the father son project "Jabaketa 2 Ultima" version 6, the ultra fast, lightweight and very capable 19mm rocket 360mm long for a 18mm motor at around 25g without motor, printed in vase mode except the cone, which can reach around 480m with a C6-7 rocket motor; a B4-4 motor is at least very great fun at a safe height of about 275m. The rocket is being recovered by a streamer; this rocket has the fins shaped in a way that they aren't compromised at fast descends. The rocket is tested by multiple flights. A case has been constructed and printed out of PLA HT to take the model on hikes and to enjoy it without transport damages.

There are two versions of the base available, one long one (320mm) without the need of a module and a short one for smaller printers where an additional module is needed.

There are also three versions of the cone, a standard one, one with added weight (for bigger motors) and one where there is a cavity closed by a cover secured with 2 screws for the the altimeter MicroPeak https://altusmetrum.org/MicroPeak/; this version isn't tested yet hence we don't have the device yet.

The cones are printed in standard mode 100% concentric infill, the base and the module are printed in 0,5mm vase mode. We have been using PLA lightweight.

The launch logs are being printed from standard PLA, 0,1 layer height because they are tiny. Lay them down on one opening, no support needed.

The rocket is equipped with our baffle and a streamer which we have cut a 50mm*1600mm ribbon from a emergency blanket hence it is extremely light weight and reflective (information included).

Our baffle, the right size for this rocket, is also attached. It is printed out of PLA HT with a layer height of 0,1mm; also standard PLA can be used.

Glue all parts including the baffle with epoxy or super glue. The positions of the parts can be taken of the OpenRocket file, also a PDF is attached so no need to install the OpenRocket software, which is really great.
The cords are attached with small eye bolts.
The best would be to attach the streamer and baffle as high as possible to get a very stable rocket.

An OpenRocket file is attached with all the simulation and so on (be aware that the OpenRocket file contains the 300mm tube and 100mm base), link to the great free software: https://openrocket.info/

The rocket uses an aluminium rocket mount to distribute the heat evenly, a hole has to be drilled for the ejection gases to enter the rocket (On the photo the bushing hasn't been glued to the end hence super glue instead of epoxy glue has been used :( ): https://www.raketenmodellbau-klima.de/Raketenmodellbau/Zubehoer/Ersatz-Bauteile/Motorrohre-halter/Aluhuelse-fuer-18-mm-Motoren.htm?shop=raketenklima&SessionId=&a=article&ProdNr=8060&t=23&c=85&p=85

We have also constructed a start box for model rockets: https://www.thingiverse.com/thing:6887853

You'll need also a shock cord and elastic cord:

We have been flying with these motors, B4-4 and C6-5(or 7):
