Learning about a well-established parametric Lindenblad design, adding on to it a bit, along with manufacturing and building (and using!) this version of a Lindenblad antenna was really a joy over the last couple months. I believe other satellite enthusiasts might enjoy building it too, but possibly the 3D printing is not a keen interest.
Not to make any profit but really just to share, I'm considering offering a kit as described below. Assembling this kit would result in four parametric elements that bolt onto the aluminum dipole described in the AMSAT article by AA2TX. (article available in a Google share folder; see link below)
The proposed cost of the kit would be $42.53, shipped via USPS to CONUS. A list of kit contents and costs is shown below.
If you're interested in this kit, please drop me a note to [email protected] If there is sufficient interest, I'll put together a limited number of kits and ship them out. (It's not my intent to go into the antenna business, but just to share a bit!)
As an alternate approach: please note there are commercial 3D printing services from which you can order 3D parts.

*DETAILS OF PARTS IN THE KIT* K7ZOO 3D Printed ParaLindy Support PETG printed support structure for parasitic elements in AA2TX Lindenblad antenna. Price is driven by cost of material & printer maintenance. Bulk material cost for 1 kilogram of PETG is approx. $25. The piece is 132 grams. Cost of material in this part: $3.30. Estimate a little more to support printer maintenance. $7.50
Arrow Shafts Size 2219, length 11.75 $3.62 each, $14.48 for a set of four. $14.48
Rubber End Caps McMaster PN 9753K16. 10 each (8 needed + 2 spares) $1.50
Modeling Clay 25 grams of clay. Used to hold arrows and seal against resin leaking during bonding operation. $1.00
Packing Material Bubble wrap and/or packing peanuts. $3.00
