Mosquito-like model rocket with support by ayryq

Last crawled date: 3 years, 1 month ago

Added some meshmixer support so I could slice with slic3r without filling up the inner cavity with support.
Update 1, 30-August-2016. Printed and the support worked great, did its job, but the fins printed poorly as they had no support and were very thin (so they moved around a little until they connected to the body tube). Also I hadn't noticed there was some support inside the nose cone. Version 2 will have support for the fins as well, including to either side of each fin, plus I beefed up the support inside the nose cone to add a little weight.
Update 2, 31 August-2016. Printed version 2 and the fins printed much better but the support was not very easy to cleanly remove, plus the nose cone is still pretty weird. Version 3 will be uploaded and have support structures farther from the fins, plus a solid nose cone so you can use an infill pattern from your slicer.
Update 3: Printed version 3, I'm pretty happy with it. One fin had a hard-to-remove support, but I don't think I'm going to print any more of these today. Removing the work-in-progress tag.
Update 4: I've created a v4 but haven't uploaded it. Basically I removed some of the support near the bottom of the fins. But today I launched the "v3" I printed (the one with the solid nose cone) with an "A" engine and it was quite a good flight, plus it was recovered undamaged.
Update 5 (9/2016). I launched a few of these today and while everything went fine I'm rethinking the solid nose. All my launches "core sampled" after ejecting the engine. The center of gravity needs to move farther back when the engine is ejected. I'll try to release a new version with a completely hollow nose (like the original) if I can figure out how. However it should be possible to print at 0% infill.
