PARAMETRIC TUBE END CAPS WITH V1 ENGINEERING LOGO

Thank-you to Ryan @V1Engineering for his incredible support, and of course for allowing the use of these logos!

These simple to print models have only three parameters and can be easily scaled, or modified using the original Onshape files.

NOTE - All of the models for download are a fixed size 32.4mm OD, 1.4mm Wall Thickness, 4mm End Cap thickness.   Full instructions on how to modify these files are included in the “DOWNLOAD LINK” document.    

MODEL VARIATIONS

1 - PARAMETRIC V1 FULL LOGO_LARGE

The logo size is proportional to the diameter of the tube.   This can be scaled up to any dimension within reason - it would make a nice mailing tube cap for instance, but bridging would become problematic.  

Scaling below about 20mm diameter will provide printing issues with the finer points in the centre of the logo - so the outline version might be a better choice.   

If you orient the print as it opens you should find that bridging distances have been optimised, and printing should require no support.

2 - PARAMETRIC V1 OUTLINE LOGO_SMALL

I first used a version of this cap on my Lowrider 2 and then the LR3.   The logo is now proportionally tied to the diameter of the tube, so eventually if the tube is small enough I guess it will disappear!

No special printing precautions are necessary.

3 - PARAMETRIC END CAP - NO LOGO

As the name implies, this is the one for those of us who prefer to unpick the embroidered polo player off their golf shirts.  To each his own!   Printing is dead simple - maybe a textured sheet would be nice?

4 - TWO COLOUR FOR MULTI MATERIAL PRINTING

Presumably if you have an MMU or equivalent you don't need instructions from me, which is just as well, because I don't!

I have had a lot of success manually swapping filaments on my Mk4 and CoreOne using instructions from @jonnieZG posted HERE on the Prusa Forums

HOW TO MODIFY THE FILES.

Here is a brief summary.  Please download the SOURCE CODE FILE in “downloads” for a simple set of instructions.   

You will need to open an OnShape account if you do not have one, and log in.  When you access the linked files click on the BLUE button and the file will be yours to edit!

PARAMETERS

#A_OVERALL_DIAMETER - This is the measured outer diameter of your tube - the cap will match the tube OD.  Note that the little flutes on the caps have a slight draft, making the cap tighter as it goes in. 

#B_ WALL_THICKNESS  - The drawing will scale so that the outer edge of the tapered flutes matches the wall thickness.   

If you have measured accurately this will be a snug push, or gentle tap fit. Do make a test and make any adjustments as necessary - I like to have them “bump tight” any tighter and you may not be able to get them out - any looser and they'll probably do that by themselves!

#C_ END CAP THICKNESS - This is the thickness of the cap that is visible after installation.   It's variable because there are instances where less is desirable although below 2mm will not provide a consistent result.

They are simple prints, so take your time to print a test or two so that you can get the size exact.

MATERIAL 

I've used PLA for all my caps to date and have had no issues whatsoever.
