Siboor 1515 Push Clip with Heatset Insert

I have noticed my extrusions are not consistent, if you find they are too lose when you print, (test before you place the insert, in case you need to reprint) 
You may need to scale the part up 1% 

Have you ever gotten done with a build, only to discover that you didn't preload enough nuts for non-position critical accessories?! Well I have! 

I present, after 11… ok 12 iterations, a solution to this! The work in the Siboor 1515 rails included with their Voron Zero Kits. 

I printed these with Inland ASA, at .2 layer height, 100% infill. I'm assuming since they are so small you'd want to have your printer dialed in and cooling on point (depending on your material) At 150mm/s should only take around 8-9 minutes to print one. 

Designed in Tinkercad, using Leothehuman's 1515 Extrusion Clip as inspiration.

There are two versions (Labeled) 

Easy: This one snaps in and out with ease, slides along the rail and isn't too tight. Easy to remove. 

Tougher: This one requires a little more oomph to press in, but still slides with some determination, and may require a little prying to get it to pop back out. 

Both versions use the heatset inserts that came in the Siboor kit, but I believe they match up with the Voron BOM sourcing guide listed under the Pocketwatch Category.
