Some of you have probably seen the development of 43R, a caliber that's intended to 3d printed and shot out of an off the shelf pipe. I have found an adequate parent case for this pipe as well, and it's been going great so far. Just a little plinking load for now, a single piece of 00 buck with a printed sabot. Sabot is heeled, as the pipe has no rifling or chamber. They go through a 4x4, haven't gotten to chrono them yet, but my guess is going to be somewhere around 1400-1500 fps.

I'll be testing them pretty thoroughly moving forward, and releasing process/loads if all goes well. I figured that you people would probably be more interested than the 3D2A crowd.

So, for Christmas I got my kid one of the "Blissride" branded 24V ride on jeeps. It is a pretty cheap product, but it meets my needs and he has a blast riding around on it. I am sure that this will fit some other models as well.

He is a rather small toddler, and I noticed that bumps seemed to make a pretty rough ride, even just around the yard. He's just not heavy enough to compress the suspension.

This mod replaces the rear springs with the original front ones. I used springs from Lowe's to replace the fronts. Ride height is not affected at all by this modification.

The softer springs made a massive difference in reducing the effects of bumps,.and the car performs much better on uneven terrain.

There is also provisions to add an additional spring, so as he gets heavier, I just add the new spring and do not have to make new parts.

PLA+ has held up very well, but I imagine that the summer heat might cause them to deform, so I have printed in PETG.

It has worked so well for me that I have uploaded it for anyone else interested in doing the same.

As the kid grows, and things on the car break/wear out, I will be designing and uploading more parts for this ride on. Next upgrade will be a proper wheel/tire setup once the original ones are trashed. Will get ball bearings, 2 piece wheels, with TPU tires.
