Funny you say that. I just today got my own A1 mini and have set it up. I'll be printing it myself too as soon as the filament arrives. Good luck!

Glad to hear it! I look forward to seeing your print. As for the alternate pinholes, do whatever you want. I did consider making variations and may still do so in future, but for a niche part I'm putting out for free it didn't feel worth it as it would've been a lot of work. So I just went with a set of pinholes I thought would be the most broadly useful and versatile for most scenarios. Thank you kindly! I have no idea about leakage to be honest. The test print wasn't mine as I don't yet own a printer of my own, the guy who did it doesn't own any pneumatic parts. I had 2 other friends with pneumatic parts who said they would test print it for me but still haven't... Regardless, the wall thickness is 2mm so I imagine it should be a good amount of plastic between the pressurised air and the atmosphere. Let me know if you end up testing it out yourself as I'd be interested to know the results.

https://shorjok.gumroad.com/l/airtank Hi everyone, I don't visit here often but I modeled a pneumatic air tank more suited to modern Technic dimensions and I'm releasing it to the wild here. I am aware there are a couple of other 3D printable Technic air tanks online but I wasn't satisfied with their design/dimensions personally. Hopefully this is useful to someone. :) https://shorjok.gumroad.com/l/airtank

Thanks dude, I think I might have to. Maybe I'll just make it easy to swap the diffs out with knob gears and have no gearbox. I really want the pneumatics though. I'm surprised no one's mocced it before, but then again, this thing doesn't have a single 90 degree angle anywhere. The cabin doors are a minor nightmare :'(

I've started working on a dream project of mine, a Technic replica of the RT Rover from the film Prometheus. I've loved this design ever since I saw it, but am really struggling to pick a scale to work at. Initially I started working with the 107 x 44R Tractor tyres but having bought some and built one axle IRL I've now realised this thing might be way too big for my liking. In this case I've already done a considerable amount of work on both the chassis and bodywork but now I want to downscale it... apparently typical trial trucks are limited to 25 studs max width, the width of the axle with the big tyres would be like 33 studs. Please give me your thoughts on this! Both sizes of tyre to scale to would have their advantages and disadvantages, but ultimately it boils down to the bigger version being able to be a lot more detailed with more room for functions, whereas the smaller one would be much less costly to build and probably fit better with other people's truck trial mocs. That said, the smaller one I've started work on digitally seems like it would have far less room for the necessary functions. [I need to know if there are other people in the UK interested in technic truck trials as i've never seen them done here and would love to go to an event.] In any case, the planned functions are as follows: -8 wheel drive -2 steered axles -Full array of PF lights powered by a separate battery box -5 Pneumatically operated doors with a motorised compressor -Lockable differentials [manual] -High-low range gearbox [manual, probably only room in the larger version] https://imgur.com/a/KqdcVkz https://imgur.com/a/KqdcVkz https://imgur.com/a/KqdcVkz
