Modular Case Release
🕑 Added 2020-06-03 19:55:48 +0000 UTCThis post contains all of the STL files you need to put together a 4-part modular case designed to work with OSR2.
You will need 12x M3x8 bolts to hold the modules together.
For the heater pad what I recommend is a 5V carbon fibre heating pad, of the kind that can be found on Amazon or Ebay for a few dollars. These tend to draw about 1.5A from a USB plug.
These pads are generally made from multiple layers of fabric with thins strands of carbon fibre laid between. It's best not to disturb the carbon fibres themselves as they are quite delicate; instead cut around them with a craft knife or scissors.
This should leave you with a flexible web with the power wires coming off.
The web can then be inserted into the "heater" case and held in place with heat-resistant Kapton tape, of the kind you'd use on a 3D printer bed.
This can then be stuck down with more tape.
A USB heater pad is very low power - about 8 watts - so don't expect it to work quickly. The inside of the case will heat up over a few minutes, and the sleeve inside will warm up over about 30-40 minutes. The advantage to this arrangement is that it should be pretty safe and it doesn't require a control circuit. It should also stay warm for a similar period of time with the heater off thanks to the insulating case design.
As always BE CAREFUL! As always I can't guarantee the safety of any of the parts you source or the actions you take, so it's up to you to take responsibility for your own safety.
A 5V heater pad should be pretty safe but don't count on it! Take sensible precautions. For example: never leave the heated case unattended when the power is on, and always check the temperature inside temperature before use.
Finally: I think that there's a lot of scope for innovation with this. For those of you who feel like having a go at that yourselves I have put a set of STEP files in the #maker-design-vault on Discord.
Enjoy!

Can't get this to go into the OSR Receiver, it gets to the Tlock, but needs to go in 4-5mm deeper but its to big in circumference by 0.2mm or so. Or my receiver is too small. I printed OSR2_1 Receiver Beta1. I tried printing it on my Ender and my Bamboo Labs.

What sleeves will this hold? Looking at the fleshlight turbo.

Hey thanks for the hard work again!

You can do that sure. What I show is just a suggestion.

Very nice! Thanks for the work.

Also, is the idea of cutting the extra fabric out of the pads to improve flexibility when wrapping around (why not just leave the pad as is, and wrap it around)?

Do you suggest particular infill settings for strength when printing this using PLA?

I haven't put 6V through my heater, I've been using a separate 5V power supply for my testing. I wouldn't want to encourage people to exceed the specs of a part. We're dealing with Ohms law here: I = V/R, ie 20% more voltage means also 20% more current. For power P = I x V, which means 44% more power. Is that going to be dangerous or melt the plastic? Maybe? All I can say is be careful if you try it. Hope that helps?
Heya Tempest, you appear to have mounted some 0.1" headers on the leads coming off of this. Are you hooking it up to your power tap? Think 6V would be OK?
