  1. To start working, we need to have the dimension right... So I put the two servos in CAD (it's a five minutes job, ad it will allow to work this out easily)... Digging in the smaller size, I need to understand a bit better about gears printing in very small module. I have the Marui gear set working in 0.8 (almost 32dp). Printing this scaled at 50% would probably give some indications of feasibility at 64dp (I may even use the Marui gearset scalled at 50% to make a 1/20 Hunter if it is workable). I put the gearset in Bambustudio, scaled it at 50% and printed it right in 0.08mm layer thickness, with tree supports and 100% infill. Here is the result (with a Super Wheelie idle gear and not a Hunter one) I used filament trimmed at the right length for the small bevel gear axis... And it seems it is viable :-). I check and it works... I may need to review some posts of one of my friend about printing gears at it might be even usefull here...
  2. The micro sized servo is arrived... It's really really really small :-) I will need to model this guy first and then think about the work to come... It may be very well suitable for a 1/32 size Hunter (without suspensions in the case I go for 1/32)...
  3. 3 semi-successfull prints. It always split at the same place, and suprisingly not parallel to the printing plan, but perpendicularly to it. The reason is because of tolerances in this situation. The one side I was expecting to break easily works perfectly as soon as you have more than .15 tolerances... Basically, if we rotate the printing plan of 45° and make sure that the starting point of the cross member is supported that should work fine. I reviewed the design to add material which I intend to cut post printing. And the test print is 100% success! This means : Rear suspension is possible. I'm now thinking about scale : the optimal option seems to be 1/20 (scale 1/2 compared to the original Hunter), as screws and nuts are probably the easier to source in those dimensions, and it has the advantage of allowing for more material than lower scale.
  4. Before moving on the target, we need to understand first if it is possible to print an universal joint in place and what tolerances are required for this. I first designed a universal joint around 1/2 of the original Hunter universal joint... Next activity is to try to print it and play around with the tolerance to see if feasible... And my 2 first tests were unsuccessful... It PLA, it doesn't help, and the print orientation neither... But we need to understand how interlocking can work before doing any optimsations... I guess I will have many 10 mins print today for this...
  5. Today, a few elements arrived. I had already a mini servo sitting in my stuff (an order mistake at some point, but the data says it is powerfull enough for a car, I just way the good occasion to use it - spoiler : it won't be for this project). It is small, but not small enough for 1/32. it would work good to make a 1/20 car... I have a smaller size servo on order, not sure when it will arrive, but i'm looking forward for it... ESC and RX should not be much issue, on the other side... Saying this, in the event the micro sized servo doen't work, I can probably target a 1/20, 1/24 or 1/28 Hunter (in anycases, I'm able to print a body shell mould (and possibly a bodyshell as well - even in colors eventually), and that should not be much a problem, and would probably easier for the battery as well...
  6. Somehow, CAD phase 2 of the project is almost finished, and parts are ready for the final test... That said, it's a long time i'm eyeing a Hunter on ebay, and I pulled the trigger on Saturday... It arrived today This is a tiny guy :-) 1/32. and it was never thought to be remote controlled... Time for CAD extended time! Let's try to do something out of this :-). I just ordered some tiny servos (super micro size), esc and rx. I'll look forward to find a battery as well very soon... And yes, my real target is to try to make a RC Hunter 1/32, and ideally fully printable (SLA resin or FDM). Not sure I'll keep the suspensions, I need to think about this, and there might be multiple iteration of this :-)
  7. Something arrived today while I'm wrapping up the CAD work of the Hunter / Galaxy project... Marui Hunter 1/32 That thing is really tiny... Well, can I really wrap up my Hunter project without taking care of this tiny guy? It seems we are playing extended time now :-)
  8. I said that I would test a print to see the result... The parts once the support were removed (and they were pretty easy to remove). There is not much area where you can really see issues... And assembled it gives this (and I just noticed looking at the pics I forgot to remove some supports on the reprinted key (0.2 mm tolerance as 0.1 was a bit too tight). Dims are right and everything looks pretty good... It seems I can be very happy with the result :-)
  9. Worked out a 4 part chassis, or 3 parts considering the last one is an addon... And that should print on one single plate in 8 hours on my X1C (PLA - it would be longer with PETG or ABS)... The way I broke down the chassis was basically to try to obtain the better finish possible on the visible faces... I will have to test print this at some point...
  10. A lot of work was done over yesterday and today... Everything is within the two pictures... I've also extracted all the parts STL (clustered or not). Next step will be to order parts to build a Marui Hunter Proto... One thing I still need to do is find a way to get the Chassis broken down in two parts so people can print them at home if they want, I have a few ideas and the bridge on top of the battery seems to be a good start...
  11. Last night, I launched a few additional test prints... The Galaxy Bumper is quite optimal for 3D printing. I'll print one in TPU, as I believe it will be perfect. This morning, I went with my son to the local yearly motorbike show. I came back within the afternoon, and resume the work on the clusters... I started with the front suspension. The front structure will be kept separated. I did 2 versions, as Hunter MK1 was having some different arms (no shocks hook). Then I worked out the parts for rear train, and included as well he Galaxy Shock stays, and roll cage stays... Remains : the Hunter front "shocks" parts, the proto rear "shocks" parts, the Hunter bodyshell parts (bodyhook and searchlights), and some minor corrections I need to do and still on my todo list for parts which are not in clusters..
  12. Launched a few renderings, just for the sake to see the car complete with the new bodyshell and the rollcage And I started to work out the cluster, starting by the key prototype parts... Red marks the added parts that are not going to remain at the separation of the parts... And that is going to be my whole proto set of files. The 380 version of the motor cover will inlude a specific motor mount, while the 540 is simplified compared to the 380 version, and do not include the motor mount (my assumptions is that the people who are going to be interested with those parts are already having a 540 motor mount for their Hunter).
  13. I modified some bits of the moulds - removing some useless material, and making sure we can print this sitting on a flat face while ensuring nice finish all along the areas in contact with the vacformed sheet... Some supports will be required but that is very limited at the end... Now I really need to focus on the clusters definitions...
