Introducing the HyperRack. The Expandable Filament Rack from Thinkable Creations!

✅ Expandable

✅ Customizable

✅ Strong

If you are like me, struggling with a growing collection of filament is a challenge. I loved the idea of the RepRack wall mounted filament holder, but in my smaller workshop I didn't have enough wall space. This filament storage system is expandable horizontally and vertically so you can store as many filaments as you like. Hopefully this model helps you all with the same problem that I had!

This model uses ¾" PVC pipe as well as the 3D printed support brackets. This system is expandable, meaning you can print as many support pieces and create as many rows as you want for both filament rolls as well as boxes of filament. Be sure to share your makes below!

List/Cost of Materials you will need:

You will Also Need:

• Tape Measurer
• Marker

I purchased 10 foot lengths of ¾" PVC pipe from my local hardware store for around $5.50 a piece. I bought 6 of them so that I had extra, in case I messed up cutting the lengths (I did a few times).

The rendered CAD Model in the listing photo is the Fully Supported Version of the Filament Rack. It is a bit overkill for the 3ft x4ft sized rack in my opinion, but I'll let you decide. I personally ended up printing only the minimum amount of support parts, but I always have the option of printing more!

List of 3D Printed Parts you need to print:

*Please print “Hole Test” model before starting project*

Basic Version (Minimalist):

• (x16) 4-Way Pieces

“I recommend to print all of the parts for the basic version with 4-Way parts (even the bottom, for stability). This version worked perfectly for me.”

Full Version (Max Strength):

• (x4) 4-Way Pieces
• (x12) 5-Way Pieces
• (x4) 3-Way Corner Pieces
• (x12) 3-Way “T” Pieces

“Use this version for a super strong rack more than 4 rows tall.”

Lengths of ¾" PVC Pipe you will need to cut:

“The maximum length for the filament holding pipe that I recommend is 34in. Any longer and the pipe starts to sag. The total space available will be 32in which will hold around 10-11 rolls/boxes for each row.”

Basic Version:

• (x8) 34 inch length
• (x12) 8 inch length
• (x8) 2 inch length

Full Version:

• (x10) 34 inch length
• (x24) 8 inch length
• (x24) 2 inch length

Hole Sizes:

Inevetably as with all 3D printing projects, you will need to do some test prints. I have pre-measured and adjusted the hole sizes for the pipes that I used, but they might not be exactly the same as yours. That and your printer might have different tollerances than my Bambu Lab X1-Carbon printers. So, before printing a ton of parts, you should print the “hole test” model first. Print it 2 times, once vertical with supports and once horizontal. See if they fit on the end of the ¾" pipes you have just as a double check. If they are correct, fantastic. If not, I've included the .STEP files so you can change the hole sizes in your CAD software as needed.
