Description
Have also a look at our other designs. https://www.thingiverse.com/kledolin/designs
After a lot of versions it is finally ready, the father son project "Abaketa 2 Prima" version 8, the lightweight 35mm rocket 710mm long for a 18mm motor at around 95g without motor, mostly printed in vase mode, which can reach around 400m with a D9-5 or D9-7 rocket motor; a C6-5 motor is at least very great fun at a safe height of nearly 200m. It has been tested multiple times, alone the orange prototype on the photograph has more than 25 flights. The yellow one on is the up-to-date version which also flies great in heavy wind conditions; don't forget binoculars then, hence once we nearly had lost it, because it was drifting away more than 600m according to gps coordinates. Without binoculars we wouldn't be able to locate it.
The base and nose cone are printed in standard and the modules i.e. tubes are printed in 0,6mm vase mode. We have been using PLA lightweight. On the base you will get some stringing with PLA LW but it doesn't matter hence nearly everything is inside the base.
A Z-axis of 250mm is needed. If someone would need shorter tubes than 250mm, comment.
The both templates can be printed in TPU, secured to the rocket via tape and then sprayed over with paint.
An OpenRocket file is attached with all the simulation and so on, link to the great free software: https://openrocket.info/
Glue all parts including baffle of your choice with epoxy. The positions of the parts can be taken of the OpenRocket file.
The cords are attached with small eye bolts.
For people which won't download the software I have attached a PDF file; all masses are real measured masses. The best would be to attach the parachute and baffle as high as possible to get a super stable rocket. Even with a D9 motor the rocket is very stable at over 2 cal/10%.
It is equipped with our baffle (parachte protection) which can be best printed in ABS or PLA HT (PLA should also be possible, hence it is far away from the motor mount, in the upper module.): https://www.thingiverse.com/thing:6982883
The prototype is using this baffle: https://www.raketenmodellbau-klima.de/Raketenmodellbau/Zubehoer/Ersatz-Bauteile/Baffle-Fallschrimschutz/Baffle-35mm-Fallschirmschutz.htm?shop=raketenklima&SessionId=&a=article&ProdNr=8101&t=23&c=1601&p=1601
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
It uses a 35 or 40cm parachute which can be fabricated (templates included) or bought: https://www.raketenmodellbau-klima.de/Raketenmodellbau/Zubehoer/Ersatz-Bauteile/Fallschirme-Flatterbaender/Fallschirm.htm?shop=raketenklima&SessionId=&a=article&ProdNr=7010&t=23&c=88&p=88
Our prototype is using this high quality parachute which survived all the tests and a hard crash landing without any damage: https://www.raketenmodellbau-klima.de/Raketenmodellbau/Zubehoer/Ersatz-Bauteile/Fallschirme-Flatterbaender/Fallschirm-35cm.htm?shop=raketenklima&SessionId=&a=article&ProdNr=8589&t=23&c=88&p=88
You'll need also a shock cord and elastic cord:

Our rocket stand can be downloaded here: https://www.thingiverse.com/thing:6984001
We have also constructed a start box for model rockets: https://www.thingiverse.com/thing:6887853
Soon other rockets are going to follow. Please comment if you are going to build the project.
We have been flying with these motors, C6-5 and D9-7(or 5):
