Disc Golf Putting Practice Target -- all sizes

Introduction

A simple ball-shaped target to serve as a visual reference for your putting practice. It clamps on a single link in the chains, and gives you a point to aim at.

Will it fit?

The target is designed to really fit around a single chain link, and allow free movement with respect to adjacent links in the chain. On baskets I tried, this results in target diameter of approx. 3 cm (1¼"). Different manufacturers use different-size chains. I will do my best to maintain a table here, and add missing sizes. If you want to help, send in your dimensions. They are the outside measurements of the oval-shaped chain link in your basket. Also measure the link wire diameter. For the time being, I have the following:

Printing

The model prints in halves, that are not fully identical. One side has a hex shaft to hold your nut, the other has a round aperture for your screw head. Both halves can be printed at once, or, as I prefer, in sequence (Finish individual objects) to limit stringing.

The model prints without supports, and is not sensitive to layer height, but I print at 0.1-mm layers for smoother surface finish. I print in PETG and it's almost a must if your basket lives outside. If you store it indoors, PLA will probably be fine. Be sure to use a distinctive colour.

Assembly

Two options are provided for each basket make: M4 and M5 screw. Choose whatever you have handy. The models will typically take screws 25 or 30 mm long. So, a full supported list is: M4×25,  M4×30,  M5×25,  M5×30. 

When both halves are printed, dry-test them on a single link of chain. There are guide cones on the facing sides of the half-balls, so that they automatically align as you tighten the screw. Just put a hex nut into the hex-shaped hole, thread a screw through the other, and screw tight.
