PETG HF

Description

This is a ball-mount adapter built around the AMPS 30 × 38 mm mounting pattern, provided in both 17 mm and 20 mm ball versions via separate print profiles.

Many mobile-electronics accessories—phone mounts, GPS units, camera brackets, small displays, etc.—use the 17 mm ball standard and/or the AMPS base standard. The popular (but pricey) ProClip/Brodit car-mount adapters often use the AMPS standard. There are also various available ball/socket mounts that work with Magsafe.

A 20 mm ball is used on some Arkon mounts, certain motorcycle and powersports holders, and various heavier-duty phone/tablet mounts.

Also see my socket adapter, available in 17 mm ball size (20mm coming soon), which mates with this ball adapter. In combination, the two parts form a swivel mount between two AMPS-compatible components, such as a bracket and a phone holder.

The model has internal geometry intended to maintain strength when printed upright. PETG has seemed strong enough, but for added strength you can screw an M4 flat-head bolt (25–30 mm long) into the center bore of the part. This bolt can also be used for mounting the cylindrical-base version.

There are three versions on each plate:
• AMPS-plate version – includes the four AMPS mounting holes (30 mm × 38 mm)
• AMPS-plate version with nut traps – recesses to receive M4 nuts
• Cylindrical-base version – has a 28 mm diameter base that can be glued to another piece or attached with the central M4 bolt mentioned above

In my limited testing, Bambu Lab PETG HF has produced parts with by far the best clamping and smoothest swivel friction in this application, compared to PCTG and other PETGs.

perfect fit in PETG reinforced bolt will make this stronger than anything on amazon!

@Turken108

How did you get the sphere to print so good? I made a camera mount and couldn't get the bottom side of the sphere to print that good

The designer has replied

@user_633976383

I used PLA and the sphere turned out really smooth.

@chronicity

Turken108, it hasn't been a problem for me using the settings in the print profile. The transition from the cylinder to the sphere is designed to keep the overhang angle from becoming too shallow.

@Turken108

Replying to @chronicity :

I didn't mean your print profile printed bad. I just meant i made something similar to attach a camera to a dog kennel and was wondering what trick you used to get it so smooth when printing a sphere. I was using BL PETG and it wasn't printing thay great on the bottom side of the sphere
