More Mugen Bulldog , transmission housing done .
For the Eagle eyed this one has a few minor additions to optimise it for FDM printing.

It's difficult to see when you can't compare with the original part, my friend :-)

There are several paired posts that come out of the top and bottom of the transmission casing , I just added a web between them and extended it to bed level (only 1mm) , I also put a 45 degree chamfer on some overhangs

I suspected that, but as I don't know the Mugen Bulldog, I wasn't sure :-)

I just found that I can fit the PB Mini Mustang chassis on the P1P print bed in one piece :D

Mini Mustang chassis in CF PETG , going to work on a diff that uses Hotshot bevel gears as parts are very scarce now for the Mustang

Well, the Big Bear ran with bevel gears printed in plain nylon in my Bambu Lab X1C for quite a while without a single issue... So yes, it should be possible (and I did not used a 0.2 mm nozzle for that).

I'm planning on using the metal diff gears and outdrivres from the Hot Shot and just printing the toothed pulley and bearing adapters .

Hot Shot diff gears in a mini Mustang compatible diff , will need axles to match the more common dog bone size of the Hot Shot , uses 5x10 bearings and an adapter to fit the 13mm hole for the stock Mini Mustang bearing .

Just received an engineering plate and some PA6 CF from Bambu Lab yesterday , dried the filament for 20 hours and my first print has started :D

PA6 CF prints so well , printed some Mini Mustang arms and once I pressed in the ball studs they are free and smooth , often when you print a ball joint you have to hone them a bit , very impressed with the dimensional accuracy .

These arms and hubs are modified to use HotShot dog bones and axles to make a set to complement the Hotshot diff components .

Interesting... I have some PA12 HT CF and PETG CF at home but did not tried to print yet with them... Time will come, as I have something in mind, but right now I'm focused on something else... I also heard about PC being very interesting for RC, and I must recognize I'm tempted to try... And the PA6 CF as well...

Did you print with the 0.4 mm nozzle?

We use PA6 carbon for our no prep drag racing body mount/caster blocks and they hold up great at 100mph but the print is not the prettiest.

Yes it's a 0.4 mm nozzle , one important thing is to dry the filament first even new out the sealed package , I dried this roll for 20+ hours before printing and the result is that xcellent

That finish is very like the Esun CF Nylon I was originally using , it was strong but more flexible and never had a glossy finish , the BambuLab PA6 CF has that nice satin shine and it has that crisp clatter when you drop it , expensive though £37 for half a kilo !

I was aware for the drying, with Nylon, it should be almost the standard procedure...
