I reviewed a bunch of them out there in the market and tried to improve upon them. That may be subjective but I find this one to work extremely well. Simply lay a stem into the stripper using the slot closest to the size of the stem, squeeze closed the stripper, and pull the stem. So much better than using your finger when doing a large volume of plants.

Printing

This product was designed for a 0.4mm nozzle, a 0.2mm layer height and the following settings:

Wall Line Count = 4 ( 4 x 0.4mm = 1.6mm walls )
Top and Bottom Layer Count = 5 ( 5 x 0.2mm = 1.0mm top and bottom )
Infill = 40%, Cubic
Ironing = OFF (not needed)
Support = All required support is designed into this product
Brim = NO (a brim can complicate details of print-in-place parts and parts printed close together – If you have to use a brim, set it to “outside only”)
Material = Food grade PETG recommended (any material should work fine)
Print Orientation: As shown below.

Assembly Notes

No assembly or post-print processing is required.

My goal was a small structure that I could deploy in the fall and put in storage in the spring. I also wanted to use as many low-cost off-the-shelf materials as I could to make it affordable and convenient to build.

The resulting design requires only two printed parts (shown in the images as green (Figure 1) and red (Figure 2) parts). The green part is a PVC pipe to roof closure connector (6 required). And, the red part is PVC tube end to PVC tube connector (4 required).

The standard 1/2″ PVC tubing and its standard fittings provide most of the structure. However, I needed the two parts I designed so that I could attach the roof and also so that the entire structure could be easily assembled and folded for storage.

To make one of these structures requires 1/3 of an 8-foot roof panel and two 10-foot lengths of 1/2″ PVC. Also, the roof panel closures came in a set of 6. So I used one roof panel and one set of closures to make 3 structures.

Bill of Materials (Part labels referenced in figures 5 and 6):

Printed Parts
[A] 3D printed 1/2″ pipe-to-roof snap-on connector, 6 required.
[B] 3D printed pipe-to-pipe end snap-on connector, 4 required.

Building Supply Sourced Parts
[C] 1/2″ PVC corners, 8 required (you can use T connectors also for the back frame if you have them).
[D] 2 PVC Closures for roof panel [E], sold as a 6-piece set.
[E] 1/3 of an 8-foot Polycarbonate roof panel, 1 required

Two 10-foot lengths of 1/2 PVC Pipe Cut as follows:
[F] 6 pieces, 52cm (20.5″) for entire front frame and front-to-back connectors.
[G] 2 pieces, 72cm (29.5″) for back frame uprights.
[H] 2 pieces, 59cm (23.25″) for back frame cross members.

Fasteners
[I] 6 stainless steel screws, I used #6 5/8″ because that was what I had laying around. Pretty much anything close to that will do.

Because the front frame is slightly narrower than the back frame, the front frame can nest inside the back frame allowing the structure to fold down quite compactly.

The only fasteners I used are the 6 screws (part [I]) to connect the roof panel and closures to the pipe-to-roof connector (part [A]). I did not need to use any solvents (adhesives) on any of the PVC connectors. They seem to have a pretty good friction fit.

The pipe-to-roof connector (part [A]) snaps onto the PVC pipe so it can be removed as needed. The pipe-to-pipe end connector (part [B]) snaps onto both pipes and can be readily removed as needed also.

Printing

Material: I choose to use PETG for its durability and flexibility. I suspect you could make these parts with PLA as well but they may not last too many winters.

My Settings:
Layer height = 0.2mm
Line width – 0.4mm
Wall count = 4 (1.6mm)
Infill = 40%, but it is irrelevant as max wall thickness is 2mm.
Support = Designed to print without supports.

Orientation: As shown in the screenshots.
