3D model description

This is a 25.4mm pivotal seat post that I designed. Should fit most BMX frames. Older or custom MTB frames.

It's meant to be fully inserted into the frame, so the bolt adds extra strength to the clamping part. The clamp would press on the seat bolt and not just the plastic.

Length 26mm
Weight (according to Cura slicer) is 34g or 1.2oz

I printed it out of Pla Plus but I haven't done excessive riding with it.
207degrees

Threads are plastic so don't overtighten, grease is suggested.

Good luck!
Please add pictures.
