Hey Blue dot sub pilots!
I saw the fantastic news about the STL being available for purcase and did yesterday pretty much as soon as I saw the notification!
when I drag and drop the STL files into cura I can't help but feel the scale may be off a tad? these are the STL's straight from the unzipped folder. Is there a scaling thing I missed?
Davy, I’m so glad you’re able to use these! Yeah, the scale on these is off. The small pieces you’ll want to multiply by 10, and the large camera mount you’ll want to multiply by 0.1 Let me update these for future prints! -Costas
Hey Costas, cheers for the info!
Been dialling in my settings for my ender 3 and getting used to running prusa slicer over cura but slowly and surely getting more parts printed out! been using PETG, found for ROV parts it makes them pretty strong, and using a 0.6mm nozzle too just to up the speed and strength of parts, used some brackets and smaller parts as test pieces and got the main deck printed today!
Any advice for the rails? They're going to be pretty tight in the ender 3's print area!
This looks awesome Davy! I've always wanted to make a yellow one, very excited to see how your finished ROV looks. The rails are a bit unweildy because they're getting the max possible length out of the ender3. The way I print them on mine is to flip them upside down (so that top tab gives you lots of surface area to stick to the bed) and angled ~45 degrees from corner to corner across the bed. You might have to move the shape around a bit in Cura to find the sweet spot.
Here's a screenshot of my cura setup, as well as a photo of the actual rail printing out my ender3
Cheers!

Hey Costas,
Again thanks for the info, managed to get both rails printed out, nearly got the bulk of the frame printed out and then moving onto all the electronic stuff :) I'll be using an Arduino Nano as a programmer for the BLHeli ESC's I have, found a guide along the lines of what has to be done - https://docs.beobachtung3d.com/how-to-flash-blheli-esc-for-bidirectional-operation.html
Its getting there though once the maindeck is bolted together I can see about getting things mounted and see about making adaptors so that standard brushless motors fit the frame! I'd like to mount the vertical thrusters at closer to a 45 degree angle too, to maximise lateral movement when one is fired you can cheat into a lateral left or right movement so you can laterally move and turn at the same time
First things first get it all printed and fitted and take it from there!
looks great!! Also, thanks for those links on flashing BLHeli escs for bidirectiona, I’ve always wanted to try that for an ROV and I’m hoping to follow in your footsteps soon!
Are you planning to print out custom mounts? Also - do you have any plan to waterproof the brushles motors, or are you planning to experiment with it?
Good luck Davy, im excited to see your progress!

I’m printing my first Rov, what infill is advised? Due to pressure change underwater?
