[ Update: April 11th, 2021 ] Added feet for the extrusion, to be printed in TPU/TPE :)
Peg strength failed. Tolerance is ok, but removing the supports broke the piece. Redesign in progress. ### UPDATE2:
Pegs redesigned, sturdier, 90 degrees, so universal for both sides. Boxes will now not be fully horizontal, but that should not be a real problem.
Also corrected a few numbers in the parts list. ### UPDATE3:
I ordered extrusions for a double rack, expect them delivered in 2 weeks, will build a rack and post pictures :) ### UPDATE4:
finally added the appropriate attribution
currently printing and testing new end-cap design (the part that goes into the extrusion, that is. The visible and functional part, the 10 degree slope, stays the same.) ### UPDATE5:
Removed the references to "left" and "right" peg, as they are no longer available.
Added an "alternate" version of the extrusion cap. This one stays in place better than the original. ### UPDATE6:
Materials received, rack built. Some issues I need to address;
the improved extrusion cap has longer "grippers" taking space away from the pegs in the extrusion. This combined with the pegs needing to be slightly longer means room for less pegs in total, so, I will switch from 250mm to 300mm extrusions to compensate. ### UPDATE7:
"alternate" cap is now cap v4, removed the old version as this "alternate" version is sooo much better.
Rotated the gripping part of the extrusion cap and lengthened the pip in the middle. Cap now stays on firmly. You should still print v4 for in between de extrusions, but the rest should be v5. Updated the print list accordingly. ### UPDATE8:
updated the rod; now fits snug so it actually helps the pegs to stay down as well, some of the pegs are loose, some snug, I don't know why, they printed all at the same time ... one of those mysteries, I guess... The rod helps to keep them in place and fills the remaining 6mm of space ;) ### UPDATE9:
Added feet for the extrusion, to be printed in TPU/TPE :) ### Hardware requirements:
the V-slot extrusions you need are the black ones, often called "European measurements", the silver coloured sometimes have smaller gaps. The type you need is like those used on Creality printers. Or you can print your own extrusions if you can print that large :).
I ordered these to length: https://aliexpress.com/item/32919571212.html ### Hardware list for a single rack;
2x 250300 mm extrusion
16x M4 T-Nut #### and print
2x 90 degrees coupler
4x Foot (TPU/TPE) ### Hardware list for a double rack;
3x 250300 mm extrusion
28x M4 T-Nut #### and print
4x 90 degrees coupler
6x Foot (TPU/TPE)
see print bed screenshot for printing orientation and supports
*1) the pegs need support above 50 (!) degree overhang, if set lower, the stilts get support as well, which is not needed; you should be able to print 45 degree overhang without supports.
Printer Brand:
Creality
Printer:
Ender 5
Rafts:
No
Supports:
Yes
Resolution:
0.20
Infill:
40%
Filament: REAL PLA Red
Notes:
I printed the couplers in Jupiter Black PLA (123-3d brand) and the pegs/caps/rods in a bright red PLA by REAL.
The feet I Printed 40% TPU but as they are printed on their side, they are about 100% anyways. If you print them as in the STL, you will need supports but you can then print 40% for some squishiness.
Please send me your feedback in the comments :)
Credit where credit is due
Although the idea for the rack is my own, and if not original, that is totally by coincidence.
However; I cut some corners by using models of other people, so, here is the list;

for the 80 degrees version:
I cut the 40x40x20 in half under a 45 degree angle, rotated the second part 10degrees and "glued" it back on, changed the pointed end so it doesn't interfere with the extrusion cap and straightened the diagonal to make it neat.
for both the 80 and 90 degree version I created a little recess to allow usage of an 8mm bolt. Otherwise a 10mm bolt and a 1mm washer are needed to make sure the part is secure instead of the bolt digging into the extrusion.

In both cases, only the "plug" part is used, the visible (external) part is my own "design"

I used this just for visuals.
If you want and feel generous, please send me a tip on paypal.me/remonpel. I will send part of that tip to the creators abode.
